Question

There are 4 gallons of milk in the refrigerator, Mrs. White uses 1/5 gallon of milk to make a batch of pancakes. How many batches of pancakes can she make with 4 gallons of milk?

Answer 1

the answer is twenty

Answer 2

She can make 20 batches of pancakes with 4 gallons of milk.

Solution:

Given that,

Quantity of milk in refrigerator = 4 gallons

Quantity of milk required to make a batch of pan cake =
`(1)/(5) \ gallon`

Need to determine how many batches of pan cake Mrs.White can make using 4 gallons of milk.

Number of batches which can be made by
`(1)/(5)` gallons of Milk = 1

So number of batches which can be made by
`(1)/(5) * 5=1 \ gallons \ of \ milk = 1 * 5=5`

So, number of batches which can be made by 4 gallons of milk = 4 multiplied by the number of batches which can be made by 1 gallons of milk =
`4 * 5=20`

Hence, she can make 20 batches of pancakes.
