Buy a TI-89 graphing calculator, that'll do the trick.

(1) (a-6)/5=7/12 By cross-multiplication,we get12(a-6)=5*7 =>12a-72=35 =>12a=35+72=107  =>a=107/12=8 11/12 ans       (2) 8/(b+10)=4/(2b-7) By cross multiplication,we get 8(2b-7)=4(b+10)  => 16b-56=4b+40  => 16b-4b=40+56  =>12b=96 =>b=96/12=8  ans. (3) $3/lb = 300cents/lb=300/16 cents per oz,=18.75c/oz ans  (4)5cm/min=5*60*24*7 cm/week=(5*60*24*7)/100 =504m/week  (5) 1milein 4 minutes = 1/4miles in 1 minute=(1/4)*60 or 15 MPH  (6) 5280 ft. in 1 hour=5280/1760 or 3 MPH  (7) p/20=(p-4)/5  =>20(p-4)=5*p  =>20p-80=5p  =>20p-5p=80  =>15p=80  =>p=80/15=16/3=5 1/3 ans.

(9) (q-11)/(q+13)=2/3 by cross multiplication 3(q-11)=2(q+13)  => 3q-33=2q+26  => 3q-2q=26+33  =>q=59  ans,  (10) 12/32=20/? By cross-multiplication,we get 12*?=32*20  =>?=(32*20)/12  =640/12=53  1/3

This is actually elementary math. If you remember the order of operation, it helps. \n\nStep 1: Do the part of the problem in the parenthesis.\n  Example: (4/3)= 1.3333333333 (you get where this is going)\n\nStep 2: Take that answer and multiply it by the named multiplier.\n  Example: 1.33333 * 12= 16\n\nStep 3: Take the result of that transaction and devide it by the named devisor. For this method don't use the fraction way, and don't use a calculator. Do a basic devision problem like you were taught in the 3rd grade using the "bracket."\n  Example: 16/13 = 1  (13 goes into 16 1 time)\n\nStep 4: Subtract the 13 from the 16 and it will give you your remainder.\n  Example: 16/13 = 1   16-13= 3\n\nThe answer when written correctly isn't with a decimal but would look like this- 1 R3.\n\nAlso for a little note for this- Order of operation:\nP (parenthesis)\nE (exponents)\nM (multiply)\nD (devide)\nA (addition)\nS (subtraction)\n\nHope this helps!

I would like to be able to give you the answer but I don't think I would be doing you a favour.  If you are to get practice in division, it is better for you to work it out on your own.  Does your teacher know that you are getting homework answers here on Yahoo?

You won't find anything on the Internet that it explains things more clearly than your math book.  The only way to get help beyond that would be to ask questions directly to a teacher or tutor.\n\nYou probably should have been asking those questions sooner than the night before the final exam.

Start with demonstrating the multiplication of fractions through physical models.\n\nSplit a rectangle in half.  That is 1 x 1/2... because you are counting that one thing 1/2 time.\n\nThen split the 1/2 into 1/2.  1/2, counted 1/2 time, is 1/4.  See it?\n\nOK, so... through whole numbers you have already demonstrated (and they should already have shown true comprehension of the idea) that division is the inverse of multiplication. So...\n\n\n1/2 divided by 2/3 is the same as 1/2 x 3/2 because that is the inverse. Division of whole numbers is a reduction of value... division of fractions is an increase of value.\n\nAlso, try this with decimals.\n\n1/10 divided by 4.\n\n1/10 divided by 4/1.\n\n1/10 x 1/4 = 1/40.\n\n1/40 = 0.025.\n\n   ____\n4 |0.1     = 0.025.\n\n25 x 4 = 100\n\n2.5 x 4 = 10.0\n\n.25 x 4 = 1.00\n\n.025 x 4 = 0.100\n\nStart to see the pattern now?

Make 2 7/15 an improper fraction, flip it over to its reciprical and mulitply the two.\n\nBoy...I hope I got that.  *bits fingernails*

Be familiar with the divisors of small numbers.  Learn to quickly look at two numbers and know if one is the sum or difference of two numbers that multiply to the other.\n\nBe able to do arithmetic in your head.\n\nLearn how to do synthetic division.\n\nPractice on many examples.

in many cases, you need innovative thinking.. Consider this:\n\n250*844 = 250*(4*411) = (250*4)*411 = 1000*411 = 411000\n251*844 = (250+1)*844 = 250*844 + 1*844 = 411000 + 844 = 411844\n\n37*123 = 37*3*41 = 111*41 = (100+10+1)*41 = 4100+410+41 = 4551\n\nsometimes, do not oversimplify...\n105*598 = (100+5)(600-2) = 100*600 - 100*2 + 5*600 - 5*2 = 60000 - 200 + 3000 -10 = 62890 (not good)\n\n105*598 = 105*(600-2) = 63000 - 210 = 62890 (better)\n\nThe key is, you have gotta practice a lot.\nFor example, when I see 111*41, I wrrite down in a peice of paper like this:\n\n(* = space)\n41**\n*41*\n**41\n----\n4554

Multiplication and division are basically just a matter of memorization.  I know if you're just learning it, its hard.  I remember having trouble as well when I first started.  But keep at it.  It will get frustrating at times, but keep at it.  The problem with math is that as you go farther, you need to remember everything you've already learned.  But otherwise, it can be real easy.  Just keep at it and you'll do fine.

For your exam, I think tips would be helpful to you more than the wishes. Please take care of the following things in mind. \n\n 1. Have good sleep on the day before the examination.\n\n 2. Take a light breakfast on the day of examination\n\n 3. Ensure that u have all the stationaries and hall ticket  before leaving your home to examination\n\n 4. Start for the examination earlier than ususal, to avoid last time panics.\n\n 5. Sit and relax yourself in the exam hall before the commencement of examination.\n\n 6. Make sure that u don't have any papers(which may be considered as illegal in most examinations, except few open book exams) in your pockets or purse in the exam hall.\n\n 7. Get the Question paper and answer script and make sure that both are in good condition and there is no misprints or damages.\n\n 8. If possible, read the question paper completely at first quickly. This will give you an idea about which part u know, which u r not feeling confident.\n\n 9. Start answering from the questions which u know very well. This gives a good impression about u to the person who is correcting the paper. (Remember, u don't have second chance to make the first impression).\n\n 10. Write the answers clear and legible. So, that it is easy to read and make the person, who is correcting the paper, comfortable.\n\n 11. Make sure that u will be able to answer all the questions within the limited time.(This u have to plan earlier itself, based on the question pattern and exam).\n\n 12. Atlast, make sure that u have written all the answer and tied (if applicable) all the answer scripts in the orderly way.\n\n 13. Mostly, try to use the full duration of exam time. Don't leave too soon or hurry till the last moment. Adjust ur time, so that u will be using the full duration of the exam.\n\n 14. If time permits, finally revise the answer scripts.\n\n 15. Give the answer scripts (and QP also if applicable) to the invigilator and leave the hall. \n\n 16. Generally, don't discuss about the answers with your friends after exams are over. ( If u feel that ur answers contradict with your friends,this may affect the next exam preparation. U can always discuss these things, after all the exams are over).\n\n \n  These are just guidelines to how to write an exam from my own experience, which i have been following for  more than 10 years. Hope this may help u. All the best for your exams. \n\n\n  Try not to become a man of success, rather try to become a man of value.

In multiplying you have to multiply the numerators and demoninators and simlify. and in dividing you have to find the resiprocal of the second # by switching the numerators and demoninators and then you multiply the #s. Peace!

use the order of operations, so first the multiplcation. so\n\n2 + 2 - 3 + 96/2\n\nThen divide by two\n\n2 + 2 - 3 + 48\n\nAdd the twos\n\n4 - 3 + 48\n\nSubtract\n\n1 + 48\n\nAdd and get\n\n49
