Question

Here are the ingredients needed to make 12 shortcakes.

Answer 1

She makes 30 shortcakes because if 10ml of milk makes 12 shortcakes than double that makes 24 shortcakes but that is only 20ml of milk to to make up for the other 5ml you need to half the 10ml so half of 12 is 6 so 25ml of milk makes 30 short cakes (hope that makes sense)

Answer 2

10 goes into 25 2.5 times. Liz is multiplying the recipe by 2.5.

So we’ll multiply the amount of shortcakes it makes by 2.5.

12 x 2.5 = 30
or 12 + 12 + 6 = 30

Liz makes 30 shortcakes.
