Question

To find the difference of 7 - 3 5/12 how do you rename the 7?

Answer 1

We have to find the difference of 7 - 3 5/12. We will rename: 7 = 6 + 1 = 6 + 12/12 = 6 12/12. Then we will calculate: 6 12/12 - 3 7/12 = 3 7/12 ( we are now able to subtract the whole number from the whole number: 6 - 3, and the fraction from the fraction: 12/12 - 5/12 ). Answer: 7 = 6 12/12

Answer 2

3 5/12 is a mixed number, where 3 is a whole number and 5/12 is a fraction. Now you can tansform 7 in a mixed number with a fraction that contains 12 as denominator. The easiest way is using the fraction 12/12, which means that you make 7 = 6 and 12/12. Now you can subtract 6 12/12 - 3 5/12 by subtrancting the whole and the fractions by separate. 6 - 3 = 3 and 12/12 - 5/12 = 7/12. So the answer is 3 and 7/12 = 3 7/12.
