How do you turn a decimal into a fraction?

Answer 1

To convert a simple decimal into a fraction, you have to go through three steps. First count the number of digits to the right of the decimal. That number will be the power of ten in the denominator. Then you'll simply place the digits in the numerator over that denominator and you're done. Let's do a few.

.4 (0.4) has one digit right of the decimal. That means 101 will be in the denominator. That's 10. Now take the 4 and put it on top, and you have 4/10 for your fraction.

.82 has two digits right of the decimal. That means 102 will be in the denominator. That's 100. Put the 82 over the top, and you have 82/100 for your fraction.

.603 has three digits right of the decimal. That means 103 will be in the denominator. That's 1000. Put the 603 on top, and you'll have 603/1000 for your fraction.

.0075 has four digits right of the decimal. That means 104 will be in the denominator. That's 10000. Put the 75 on top, and you'll have 75/10000 for your fraction. (Note that there are only two digits in the decimal, and that's all we need in the fraction.)

put it over a denominator that is used when saying it

ex .1= 1 / 10 = one tenth

I'm going to assume you mean how;

.1 is one tenths 1/10

.01 is one hundredths so 1/100

.001 is one thousandths so 1/1000

.0001 is one ten-thousandths so 1/10,000

and so on
