It is very simple \nNow lets begin from the percent\n\nPERCENT MEANS PER HUNDRED\n \nPLZ READ CAREFULY IT"S VERY IMPORTANT PART\n\nU might know how to find out the equivalents of a fraction\n\nlet me give u an EXAMPLE\n\n    1/2  =  2/4  =  4/8  =  8/16 etc\n\nKEY POINT: we can find out the EQUIVALENTS of a fraction by multiplying both numerator and denominator by the same number. In above example i have multipied both the numerators and denominators of each fraction with "2".\n\nSO NOW LES GET TO THE PERCENT\n\nwhile finding out the percentage of a fraction u have to think that u r actually trying to find out the fraction's equivalent. But that is a particular equivalent with denominator "100"\n\nEXAMPLE\nFind out the percentage of 1/2\n\n1/2  =   x/100\n\nthe denominator "2" has to be multiplied by "50" to become   "100". So the numerator must be multiplied with "50" too.\n\n1/2  =   x/100\n\n1*50 =  50\n2*50 = 100\n\nthus we get \n1/2  =  50/100\n\nwhich is equal to 50%\n\ntell me if u have understood by submiting another question.

Do you want to do it by calculator or by hand?\n\nIf by calculator, just take the top number divided by the bottom number to get your decimal:\n\n>> Fraction:  3/4 = 3 ÷ 4 = 0.75\n\n>> Mixed number:  Put the whole number to the left of the decimal point, then divide the top number by the bottom number to get the portion to the right of the decimal:  Example 8 2/3 = 8.666...\n\nIf by hand, multiply top and bottom to get 100 in the bottom (if possible) ... for example, multiply 3/4 by 25/25 to get 75/100 = 0.75.\n\nIf it's not possible to get 100 in the bottom, then just do long division to get the decimal.\n\nHope that helped a little!\n\n~ ♥ ~

The first part of the question is telling you that you have a circle that has a circumference of 56cm, but it could be off by 1.2cm, give or take. The want you to find what percent it is.\n\nFor the math: (1.2/56)*100 \n\nor, using proportions  1.2/56  =  x/100\n(Setting the fracions upright, cross multiiply, solve for x)\n\nFor the next one, they are saying that the circumference can be off by 3%. In this case: (3/100)*56\n\nor, using proportions: x/56 = 3/100\n\n**For setting up basic proportion, you measurments have to be on one side and your percents have to be on the other.\nmeas./total meas. = percent/total percent

OK, when you change a percent to a fraction, remember that a percent is the same as a hundredth.  So 80% = 80/100 or 4/5, and 87.5% = 87.5/100 or 7/8.\n\nIt looks like the other numbers here are already fractions.

To convert a decimal to a percent, move the decimal point two places to the right.  To convert it to a fraction, read it without saying "point".  Your example read this way would be "forty-two hundredths".  Then just write that as the fraction that it sounds like (42/100) and reduce it if asked.

to change a decimal into a fraction take the decimal lets say .56 and put to over 1 with as many zeros that there is in the decimal so it becomes 56/100 then reduce to its simplest terms....56/100=14/25  and viola!\n\nto turn it into a decimal just divid it so it would be 14 divided by 25 ...and you get .56! \n\nhope this helps :)

.47\n\n47/100 \n\nSo that you understand it, everytime you want to change a percentage to decimal, you take out the % and divide it between 100\n\nFor decimals, you take out the % and write the number you have above (here/100) 100\n\nHope it helps, have a nice day

Even though this appears simple, it is slightly tricky.\n\nPart (a ) is to convert 4&3/4 to a decimal and Percent\n\n4 3/4 = 4.75 as a decimal.\n\nAs a percentage, we can calculate\n\n4.75 divided by 100 times 100% is again 4.75%\n\n(Note: If we calculate 4.75 in relation to 1, then in percentage terms this equals 475%)\n\nPart (b) is to convert 4&3/4% to a fraction and a decimal\n\n4&3/4% = 0.0475 as a decimal and 19/400 as a fraction.

hmm..well this might be an easy fix if you have a calculator\n\nsimply multiply the total by 0.1.  the answer will be 10 percent of the total.\n\nhope this helps\n\nexample: 132.00  x 0.1 = 13.20    which is 10%

Divide top number of the fraction by the bottom number \n(1/4 = divide 1 by 4 = 0.25) That is fraction to decimal. \nTo get percentage just multiply by 100. \nSo the 0.25 becomes 25, or 25%\n\n: - )

Fractions were always the hardest for me, and I still have to do a quick check! Rather than go through each one (add, subtract, multiply, subtract, I’ll send you a really good web site. http://www.mathleague.com/help/fractions/fractions.htm

fractions into decimals\n\neasy way is 7/100 \ndivide 7 by 100 and you will get 0.07\n\ndivde mix fractions like 2 5/8\nchange into improper fraction 21/8\nthen divde 21 by 8 and you will get 2.625

One way to find the percentage of a value is to convert the percentage into a number then multiply the value by this number.\nYou convert a percentage into a number by dividing the percentage by 100: x% = x/100.\n\nFor example: find 5% of 200.\n1) Convert the percentage to a number:\n5% = 5/100 = 0.05\n2) Multiply the value by the number:\n200*0.05=10\n\nIn your case,\n1) Convert the percentage to a number:\n91&3/8% = 91.375/100 = 0.91375\n2) Multiply the value by the number:\n1000*0.91375 = 913.75\n\nYou would have $913.75

is the AT and GC proportions?\n\nfor example\n\n30% AT\n70% GC\n\nis the same as\n\n15% A\n15% T\n35% G\n35% C

6 % for the first one\n85% for the second\n\nto get that, you divide the numerator by the denominator to get the decimal.  Than you move the decimal two places over to get the percentage.

You will need to know that when you calculate a percentage of anything, it is kind of like a fraction, except that the denominator is 100.\n\nFor example, you have 7 sticks. 3 of them are red, 2 of them are yellow and the other 2 are blue. To get a percentage of the number of red sticks:\n\n(no of red sticks /  total no of sticks) x 100%\n\n...and that is how you get your percentage.\n\nOnce you have understood that this question should be quite simple. Sodium sulfite is Na2SO3.\n\n\nFirst you have to calculate the masses of all the elements in this compound.\n\nmass of Na\n= 2 x 23\n= 46\n\nmass of S\n= 1 x 32\n= 32\n\nmass of O\n= 3 x 16\n= 48\n\ntotal mass of Na2SO3\n= 46 + 32 + 48\n= 126\n\n\nHence, using the same concept,\n% of Na by mass\n= (46 / 126) x 100%\n= 36.5% (3 s.f.)\n\n% of S by mass\n= (32 / 126) x 100%\n= 25.4% (3 s.f.)\n\n% of O by mass\n= (48 / 126) x 100%\n= 38.1% (3 s.f.)\n\n\nHope you understand now!
