Question

If there is 45 ml of milkshake left .She used 1 part strawberry cream to 4 parts milk .How many ml of milk is left?

Answer 1

Given:

Remaining milkshake = 45 ml

She used 1 part strawberry cream to 4 parts milk.

To find:

The remaining amount of milk.

Solution:

It is given that, she used 1 part strawberry cream to 4 parts milk. It means the ratio of strawberry cream and milkshake is 1:4.

Let the remaining amount strawberry cream be x and the remaining amount of milk is 4x. Then,

`x+4x=45`

`5x=45`

`x=(45)/(5)`

`x=9`

Now, the remaining amount of milk is:

`4x=4(9)`

`4x=36`

Therefore, the remaining amount of milk is 36 ml.
