Question

A recipe calls for 1/4 cup of flour. Carter does not have a quarter-cup measuring cup, though he has a measuring cup that holds an eighth of the cup. How can carter measure the flour he needs for his recipe.

Answer 1

Carter can use the 1/8 measuring cup two times to get 2/8 because 2/8 is equivalent to 1/4.

Answer 2

Carter should measure two times the flour in the cup to obtain the quarter of cup he needs to the recipe.

Explanation:

To solve this problem you should use a simple equation. As Carter has a cup that holds an eighth of the cup and he need to add a quarter cup to the recipe he needs to find a factor that multiplied by
`(1)/(8)` gives as result the
`(1)/(4)` he needs, that is:

1. Let´s name x the factor and we have the following equation:

`(1)/(8)*x=(1)/(4)`

2. Solving for x:

`(x)/(8)=(1)/(4)`

`x=(8)/(4)`

`x=2`

The result x=2 means that Carter should measure two times the flour in the cup to obtain the quarter of cup he needs to the recipe.
