Question :
Lela is making peach pies. She uses 9 peaches for each pie. If she uses 18 peaches for 2 pies and 36 peaches for 4 pies, how many peaches will she need for 7 pies?
Answer :
Explanation :
As, Lela is using 9 peaches for each pie.
Thus, she used 18 peaches for 2 pies, which is 2 times 9 and 36 peaches for 4 pies, which is 4 times 9. Therefore, to make 7 pies, she would need :
Peaches used for one pie = 9
=> Peaches used for 7 pies = 9 × 7
=> Peaches needed for 7 pies = 63
Hence, she will need 63 peaches to make 7 pies.
