Answer: twelve and nine-tenths feet
Explanation:
I turned the fractions into decimals cus I find that easier.
5/8 = .625 + 2 = 2.625
2.625(4) = 10.5 (multiply by 4 because it is 4 pieces)
1/5 = 0.2 + 1 = 1.2
1.2(2) = 2.4 (multiply by 2 because it is 2 pieces)
2.4 + 10.5 = 12.9
.9 can also be 9/10ths
