Answer:
5 pounds
Step-by-step 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
