Answer:
The number of Pumpkin can used = 48 cans
The number of Green Beans can used = 16 cans
Step-by-step explanation:
The ratio of Pumpkin to Green Beans = 3 : 1
So, for every 3 can of Pumpkin, 1 can of green beans is used.
Now, the total number of John wants to use = 64
Let us assume the common factor in the ratio is m.
⇒ The number of Pumpkin can used = 3 m
The number of Green Beans can used = 1 m = m
So, the Total cans used = Number of (Pumpkin + Green Beans) can
⇒ 3 m + m = 64
or, 4 m = 64
⇒ m = 64/ 4 = 16
Hence, The number of Pumpkin can used = 3 m = 3 x 16 = 48 cans
The number of Green Beans can used = m = 16 cans
