Answer:
10
Step-by-step explanation:
10 apple pies = 4 pounds of apples
Divide both sides by 10
10/10 apple pie = 4/10 pounds of apples
1 apple pie = 2/5 pounds of apples
Multiply both sides by 25
25 apple pies = 2/5 * 25
= 10 pounds of apples
Therefore 25 apple pies will be produced using 10 pounds of apples
