Question

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,

$x+4x=45$

$5x=45$

$x=\dfrac{45}{5}$

$x=9$

Now, the remaining amount of milk is:

$4x=4(9)$

$4x=36$

Therefore, the remaining amount of milk is 36 ml.
