Answer:
90 apples
Explanation:
First, we need to find 1/3 of the total number of pies, which is the number of pies the first class made. To do this, we divide 60 by 3 (or multiply 60 by 1/3):
60 ÷ 3 = 20
This means the first class made 20 pies and that the second class has to make 40 pies (60 - 20 = 40)
1 pie needs 2 1/4 apples
To find how many apples the second class will need, we must multiply 40 (the number of pies) • 2 1/4 (the number of apples needed for 1 pie)
40 • 2 1/4 = 90
This means 90 apples are needed for the second class to make the remaining pies
