Use a calculator - numerator divided by denominator will give you the answer.

u can't get a remainder only a decimal

thats very simple to multiply a fraction you just multiply straight across. Numerator times numerator, denominator times denominator. \n\nEX: 1/2 * 1/2 = 1/4 or 2/3 *2/3 = 4/9\n\nTo divide a fraction its almost basically the same. First you take the "recipricol" of the second fraction. That just means you flip it upside down. Like so\n\nEX: 1/2 divided by 1/2 would become this. 1/2 * 2/1. \nnotice it becomes a multiplication problem now. So you work it jsut like a mult. problem\n\nheres another example to be sure. 2/3 divided by 5/6 would become 2/3*6/5 = 12/15

To divide decimal numbers:\n\n1.If the divisor is not a whole number:\n      *Move the decimal point in the divisor all the way to the right (to make it a whole number).\n      *Move the decimal point in the dividend the same number of places.\n\n   2.Divide as usual. If the divisor doesn't go into the dividend evenly, add zeroes to the right of the last digit in the dividend and keep dividing until it comes out evenly or a repeating pattern shows up.\n\n   3. Position the decimal point in the result directly above the decimal point in the dividend. \n\n   4. Check your answer: Use the calculator and multiply the quotient by the divisor.

There is a nice tutorial here: http://www.bmcc.org/nish/MathTutorials/Fractions/index.html

To do equivalent fractions, you can multiply the top and bottom by the same number and keep the basic value of the fraction the same.  For example, 1/2 = 2/4 = 3/6, etc.  You multiplied top and bottom by 2 to get 2/4 and 3 to get 3/6.\n\nNow, to add and subtract fractions, you have to give them a common denominator.  Usually this means finding an equivalent fraction of at least one of them, which is why I explained that first.  Once you have a common denominator, simply add or subtract across the top, and keep the bottom the same.  \n\nFor example, 1/2 + 1/4 --- the common denominator is 4, so you would have to change 1/2 to it's equivalent fraction by multiplying top and bottom by some number.  2 goes into 4 twice, so you'd multiply both by 2.  Now you have 2/4 + 1/4 = 3/4\n\nTo multiply fractions, simply multiply the tops, then multiply the bottoms, and reduce if possible.  1/2*3/4 = (1*3)/(2*4) = 3/8.  This cannot be reduced.\n\nTo divide fractions, flip the second one over and multiply.  2/3 / 1/2 = 2/3*2/1 = 4/3 or 1 1/3\n\nHope this helps.

4.2\n\nto figure out a number as a decimal, you just move the decimal two spaces to the left. so think of 420 as 420.00, then move the decimal two spaces to the left and you've got 4.2

Divide it using decimals then multply the decimal by 100 and that will be your percent\n\nIs it just me or did someone else use this same exact answer below.  seriously people use your own imaginations and brains.

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~ ♥ ~

I'm pretty sure it's the same as multiplying 2 fractions.  You just multiply across the top, then across the bottom, or in w/e order you like, and what you get is your answer.

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

Well, 2/5 is already a fraction.  It is a "rational fraction," which means that it is expressed as a ratio, i.e. one number divided by another.\n\nYou can also express it as a decimal fraction.  Divide 5 into 2 by the usual means you do division and you will find that 2/5 = 0.4.\n\nYou can also express it as a percentage.  Just multiply the decimal fraction by 100: 0.4 x 100 = 40%.

it's easy of means multiply something the .7  is in precent and u have to convert it into a decimal by moving the decimal point 2 spaces to the left. the answer to the problem is.9093. I think u are missing some infor u probably want a fraction like is/for = %/whole I can't do that because u have not provide me with details.

So, to convert from decimal to percentage, just multiply the decimal by 100, but remember to put the "%" sign so people know it is per 100.\n\nThe easiest way to multiply by 100 is to move the decimal point 2 places to the right:

Depends what Base you are using.\n\nIn decimal it is 1234602335680234\n\nIn Hexadecimal it is 0x123463677ABD69AC\n\nI'll leave other bases as an exercise for the student...

A decimal fraction will have 10 or a multiple of 10 as denominator.
