Problema Solution
A baker bakes 3/4 of a batch of cookies in 5/8 of an hour. How may batches of cookies can he make in 3 hours?
Answer provided by our tutors
let 'x' be the number of batches he will make in 3 hours then we have
(3/4) : (5/8) = x : 3
x = 3*(3/4)/(5/8)
x = (9/4)*(8/5)
x = 18/5
x = 3 3/5 batches
in 3 hours he can make 3 batches and 3/5 of a batch of cookies.
