Ineed to know how to solve this i’m very lost and need immediately

Let x= the number of hours he wrote. Hence the expression 8 1/5x. Let that equal the total accomplishments in an hour. So, 8 1/5x= 32 4/5. Now I like to work with improper fractions... 8 1/5=41/5 and 32 4/5=164/5. So. 41/5x=164/5 and x=164/5*5/41. The 5's cancel and 164/41=4, So x=4. Probably could do away with the last part if examined better or using a calculator.
