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.
