To change decimals to fractions, you must move the decimal place over to make it a whole number. However many places you move it, that is how many zeroes that go on the denominator with the 1. For example, 0.38 would be 38/100 as a fraction.
Nothing. I know all that I need to know.
Either you can, or you can't! It is perfectly valid to use decimals in the top or bottom. Now, if you want whole numbers, you can convert the fraction to an equivalent fraction, multiplying top and bottom by 2 in this case.
Oh, dude, you want to know the fraction equivalent to 1.35? Well, technically speaking, 1.35 is already a fraction - it's 1 and 35 hundredths. But if you want it in a different form, you could say it's 135/100. But like, who really needs fractions when you've got decimals, right?
How accurate do you want it to be? - In case you don't know it, you can't express pi exactly as a fraction, or as a square root. You can approximate it as much as you want with decimals for example, that is, you can make the error as small as you want - but never zero.
You can multiply it by the denominator of the fraction you want to turn it in to. For example, .125 * 8 = 1, therefore, 1/8 = .125. Keep in mind that only some decimals can be made into simplified fractions. For example, .453 can be represented in simplest form as 453/1000.
3056/1000 is 3.056 as an improper fraction.
There are several rules for decimals, depending on what you want to do.
Oh, dude, you want me to math? Fine, fine. So, 4.133858 as a fraction is... drum roll, please... 4133858/1000000. Ta-da! Like, who even needs decimals when you can have fractions, am I right?
Well if they are already a fraction you do not need to convert them to a fraction. If you mean "How do you convert fractions to decimals" then I can help you there. If you have a fraction you want to make a decimal you simply divide. The little bar in the fraction means "divide" So if you have 3 over 4, you simply divide 3 by 4 which equals .75.
You add it. Or you can use decimals if i have $8.50 and i want to take out $5.00 i would use decimals and same if your adding subtracting etc. If you don't know how to multiply decimals just ignore them then add them i the end, how you know where it goes? You count how many numbers are behind! Same for division except you divide.
22.5/15 15/15 + 7.5/15 = 22.5/15 If you don't want decimals you can multiply the numerator and the denominator by two to get 45/30.
Well, darling, 3.65 as a fraction is 365/100 because you move the decimal two places to the right to get rid of those pesky decimals. Reduce it down if you want, but either way, that's the sassy fraction you're looking for. Hope that helps, sugar!
