Question

Mr. Joseph Bought 9 pounds of fertilizer for his lawn. He uses 2 2/3 pounds for his backyard and 1 2/9 pounds. How much fertilizer is left

Answer 1

5 pounds of fertilizer.

Explanation:

Total pounds of fertilizer purchased purchased for lawn = 9 pounds

Amount used for backyard = 2 2/3 pounds

Amount used for front yard = 1 2/9

Amount of fertilizer left :

Total amount purchased - total. Amount used

Total amount used :

(amount used for backyard + amount used for front yard)

(2 2/3 + 1 2/9) = (8/3 + 11/9) = (24 + 11) / 9

= 36 / 9

= 4 pounds

Amount of fertilizer left :

Total amount purchased - total. Amount used

9 pounds - 4 pounds

= 5 pounds
