Question

Russ and David have a dump truck full of mulch to spread in the yard. By lunchtime, Russ has spread 3/5 mulch, and David has spread 1/3 mulch. How much more mulch do the boys have to spread?

Answer 1

1/15 mulch is left to spread

Explanation:

15/15 - (3/5 + 1/3) =

3/5 = 9/15

1/3 = 5/15

15/15 - (9/15 + 5/15) = 15/15 - 14/15 = 1/15 is you're answer

Have a great day!
