What is the answer to 7/12-1/3?

To answer this question, we need to find a common denominator for these two fractions, i. e. how can we write 7/12 in the same way as 1/3?

The common denominator for these fractions will have to be 12, because 7/12 cannot be simplified anymore - 7 is a prime number. So we'll convert 1/3 into 12ths. To do this:

1 - - - > Multiply the top by 4, because we multiplied the bottom by 4

--

3 - - - > Multiply the bottom by 4 to get 12

So 1/3 = 4/12

7/12 - 4/12 = 3/12 - - - > Complete the subtraction

3/12 can be simplified, as both 3 and 12 are divisible by 3.

3 - - - > Divide by 3

--

12 - - - > Divide by 3

=

1

--

4

And 1/4 is your answer.
