To convert a decimal number to a fraction, you put the number over 1 followed by as many zeroes beyond the decimal point.\n\nFor example:\n0.5 --> 5/10 = 1/2\n0.0003 --> 3/10,000 (four zeroes)\n0.000123 ---> 123/1,000,000 (six zeroes)\n\nIn your cases:\n0.00030889 \n\n=..... 30,889 (leading zeroes removed)\n----------------\n100,000,000 (8 zeroes = 8 places after the decimal point)\n\n\n0.00555556\n\n=... 555,556 (leading zeroes removed)\n----------------\n100,000,000 (8 zeroes = 8 places after the decimal point)\n\nNote this second one can be reduced:\n\n=.. 138,889\n---------------\n25,000,000

ill explain. to subtract or add fractions, you have to get a common denominator. to do this, you have to find the lowest common multiple of the denominators of both fractions. so what is the lowest number that can be divided by 10 and 6 easily. the answer is 30 in this case. cuz 10*3 = 6*5 = 30.\n\nso now that you know what the denominator has to be, you have to convert each fraction to a fraction that has 30 as the denominator. so for 7/10, you can multiply top and bottom by 3 to get 21/30. its the opposite of reducing the fractions. think of it this way:\n7/10 * 3/3 = 21/30.   since 3/3 =1, youre just multiplying the fraction by 1, which doesnt change anything.\n(7/10 * 3/3) - (1/6 * 5/5)\n= 21/30 - 5/30\n= (21-5)/30.... once you have a common denominator, u can subtract the numerators.\n= 16/30\n= 8/15.\n\nhope this helped. let me know if u need more help.

first get a common denominator for the (1/x - 1/y):\n(1/x) - (1/y) = \nx/xy - y/yx = \nx-y/xy\n\nnow that we have 2 fractions in fraction form, we can reduce it to one fraction by multiplying the top with the bottom over the 2 middle sets:\n\nxy (x+y)\n-----------\nx-y (y-x)\n\n\nexpand or leave it as that

Multiplying fractions is the same as taking part of the number; for example, if you want half of a half, you multiply 1/2 by 1/2 to get a quarter.  Now suppose you wanted two thirds of a half.  The first thing you need to know is, what is one third of a half?  So, multiply 1/3 by 1/2 to get 1/6.  But you know you want two of those, so you multiply 1/6 by 2.  So you did:\n\n1/3 * 1/2 = 1/6\n1/6 * 2 = 2/6 (or 1/3)\n\nOr, to put it all in one step:\n2/3 * 1/2 = 2/6 (or 1/3)

change the 4 to 4/1. \n\n4/1*-3/2= -12/6 and then you simplify\n\nfinal answer is -6.\n\nyes you can change -3/2 to -1.5 but you will find it easier in the long run to make the whole number (4) into a fraction. not all equations will be this simple and you won't be able to figure out what the next fraction is in your head.

Change them to improper fractions\n1 1/4 = 5/4\n6 2/3 = 20/3\n5/4 divided by 20/3 equals 5/4 times 3/20\n(5/4)(3/20) = 15/80 = 3/16\n\n20 divided by 6 2/3 = 20 divided by 20/3 = \n20 times 3/20 = (20/1)(3/20) = 60/20 = 3\n\n4/5 divided by 4/5 is 1.\n(Any nonzero number divide by itself is always 1.)\n\n16 1/2 divided by 6 2/3 = 33/2 divided by 20/3 = \n33/2 times 3/20 = (33/2)(3/20) = 99/40\n\n28 divided by 4/5 = (28/1)(5/4) = 35

You can subtract them by making like denominaters:\n\n3/4-1/2+2/5\n\nThe denominaters all go into 20\n(whatever you do to the bottom you have to do to the top!)\n  3x5=15 4x5=20 \n\n15/20-1/2+2/5\n\n  1x10=10 2x10=20\n\n15/20-10/20+2/5\n  \n  2x4=8 5x4=20\n\n15/20-10/20+8/20\n\nYou only add the numeraters\n\n15/20-10/20=5/20\n\n5/20+8/20=13/20\n\n\nOr do it by decimals.\n\nTo change a fraction into a decimal, you divide the numerater by the denominater. *=divide\n\n3*4=.75\n1*2=.5\n2*5=.4\n\n.75-.5=.25\n.25+.4=.65\n\nTo change .65 back to a fraction, you move the decimal over two places, 65, so now you put it over a hundred, because you moved it past the hundreth's place. 65/100. Now simplify. Divide both by 5, (becaus eit goes in there evenly.) Now you have 13/20. (When you move the decimal place and you have \n.345, you get 34.5. You can't move it three. It's the rules!)

change mixed fractions to proper fractions and then divide,\nwhats so hard?

Multiply. Remember, 'of' usually means MULTIPLY.\n\nChange mixed numbers to improper fractions:\n5/3 x 22/9\n\nMultiply fractions. To multiply fractions, multiply the numerators and use that as the numerator of the answer. Multiply the denominators and use that as the denominator of the answer. You have an answer in improper unsimplified form.\n5/3 x 22/9 = 110/27\n\nSimplify. Find factors and divide both the numerator and the denominator down to a simplified form.\nIn this case, there are no factors.\n\nThis is the improper simplified form. You may want to change it to proper form.\nIf you would like to change it to mixed number form, divide and divide the first remainder by your divisor. Then, your answer plus the answer of that (fraction form) is your mixed number form.\n110/27 = 4 (Remainder 2) 2/27 + 4 = 4 2/27\n\nYou now have the answer.\n\nImproper Form:  110/27\nProper Form:  4 2/27

the fraction is 190046141/500000000. I'm sure your teacher will accept a decimal unless stated otherwise. For the future, whenever you need to calculate the fraction form of a decimal, just count how many digits the number has call that number k. Then write the number on top of a 1 followed by k 0s. Then you can simplify by dividing common factors.

You multiply the 4/x+1 by (x+2)/(x+2), giving you 4x+8 in the numerator and (x+1)(x+2) in the denominator. For the 5/x+2 one, you multiply by (x+1)/(x+1), giving you 5x + 5 in the numerator and (x+1)(x+2) in the denominator. Now both denominators are the same, so you can add the numerators together. You end up with 4x + 8 + 5x + 5 on top and (x+1)(x+2) on the bottom. This simplifies to (9x+13)/(x-squared + 3x + 2). I don't think you can simplify more than that.

Multiplying the denominators of all the fractions would be the easiest method.\n\nHowever, if the numbers are really big and you prefer working with small ones (e.g. if you do not have a calculator), you can first find the lowest common multiple (LCM).

Use a division sign in parentheses. That way three fourths will look like (3/4).

Yes, I can solve them.\n\nLike any other fractions, find a common denominator.  Though with (a) you can just multiply everything by 7x and simplify the equation to:\n\n21 + 1 = -14x\n\nYou can do the same with (c).  With (b) it's a little more complicated, and you have to find the common denominator of x and (x + 6).  I'll leave that for you.

What the...? I don't get that fraction....but uhh, to get the square root of fractions you take the square root of both the top and bottom, and then you simplify...that's all I got...good luck and God bless...

Reduce it untill the # on the bottom is prime.\n (divide the top AND bottom by 2 untill you get a decimal.)
