Answer:
1) We can represent the number of hours using the letter "h"
8 1/5 hours + h = 32 4/5
b) Convert the mixed number to improper fractions
8 1/5 = 41/5
32 4/5 = 164/5
We rewrite the subject
(41/5) * h = 164/5
We want to make h the subject so we can multiply both sides by the reciprocal of (41/5) = (5/41)
(5/41) * (41/5) * h = (5/41) * (164/5)
h = 164/41
h = 4
