Rafi had a board that was 15 1/2 feet long. He cut three pieces off the board that are each 3 7/8 feet long. How much of the board is left?

I am confused on how to figure out the answer for the above.
Answered by Ms. Sue
Multiply 3 7/8 feet by 3.

Subtract the product from 15 1/2.

You may want to change the fractions to decimals.

How do I multiply 3 7/8 x 3?
I never multiplied with a whole number and a fraction?
Answered by Ms. Sue
One way to do it is to multiply 3 * 3 = 9
3 * (7/8) = 21/8 = 2 5/8

9 + 2 5/8 = 11 5/8

Answered by Patrick
So if the answer is 2 5/8 then would I have to take 15 1/2 and find the common denominator?

Would it then be

15 4/8-11 5/8?
But then I can't subtract 4-5
Answered by Patrick
Or would the answer just be 11 5/8?
Answered by Ms. Sue
15 4/8 = 14 12/8

14 12/8 - 11 5/8 = 3 7/8 feet of board is left
