Question
Takes 3/4 of an hour to cut 3/5 of the lawn. How long will it take to cut the whole lawn?
Answers
Steve
the whole lawn is 1/(3/5) = 5/3 as much as he can cut in 3/4 of an hour
5/3 * 3/4 = 5/4
or, keeping track of the units,
(1 lawn) * (3/4 hr)/(3/5 lawn) = 3/4 * 5/3 = 5/4 hr
5/3 * 3/4 = 5/4
or, keeping track of the units,
(1 lawn) * (3/4 hr)/(3/5 lawn) = 3/4 * 5/3 = 5/4 hr

(3/4)/(3/5) = x/1.
3/4*5/3 = x/1,
X = 5/4 h.
3/4*5/3 = x/1,
X = 5/4 h.
