Question

To Make 5 Apple Pies,you Need 2 Pounds Of Apples . How Many Pounds Of Apples Do You Need To Make 20 Apples Pies?

Answer 1

If we need 2 pounds of apples to make 5 apple pies, then we need 8 apples to make 20 apple pies. It's because:

20 apples / 5 apple pies = 4
4 * 2 pounds = 8 pounds

Answer 2

this is a direct proportionality question
the pounds of apples needed is directly proportional to the number of apple pies made
to make 5 apple pies , 2 pounds of apples are needed
then to make 1 apple pie - 2/5 pounds of apples are needed
therefore 1 apple pie requires - 0.4 pounds of apples are needed
then to make 20 apple pies - 0.4 x 20 = 8 pounds of apples are needed
therefore 8 pounds of apples are required
