Question

Gabby mowed 5 lawns last week. She mowed each lawn in 7/12 hour. She mowed the same lawns this week in 5/12 hour each using her new lawn mower. How many times longer was Gabby’s time to mow all the lawns last week than this week? Make your answer an improper fraction

Answer 1

(7/12) / (5/12) = 7/5
the ratio for all the lawns is the same as for each lawn.
