Question

A recipe for cookies calls for 3.75 cups of flour. If Irina only wants to make half a batch of cookies, how much flour should she use? Express your answer as a fraction.

Answer 1

divide 3.75 by 0.5 and then tell me what you get

Answer 2

To make half batch of cookies, Irina needs

`(15)/(8)` cups of flour.

Explanation:

To find the answer to this question, we have to transform 3.75 into a fraction, and then divide it by 2. Such number can be transformed by dividing by 100 and then simplifying, as follows

`3.75=(375)/(100)=(75)/(20)=(15)/(4)`

Now, we divide it by two

`(15)/(4) / 2=(15)/(4) * (1)/(2)=(15)/(8)`

Therefore, to make half batch of cookies, Irina needs
`(15)/(8)` cups of flour.
