This is how you solve it
you need a common denominator for 1 1/2 and 2 3/4 so you can do 4
1 1/2 •2= 1 2/4
so 1 2/4 + 2 3/4 = 3 1/4 then you add 2 so 5 1/4
the answers would be - 5 1/4

First, find 20% of 5 hours. 20% is also 1/5 of something, and 1/5 of 5 is 1.
Multiply 5 by 3 for the 300%, getting 15 hours, and add 1 for the 20%.
He spent 16 hours on the project. Hope this helps!
