Question

A bread recipe calls for 1/3 cup of butter. You want to make 1/2 of a batch. How much butter do you need?

Answer 1

If you want to make $\dfrac{1}{2}$ of a batch and a bread recipe calls for $\dfrac{1}{3}$ cup of butter, then you should multiply the fraction needed to make the whole batch by the fraction of a batch you want tot make:

$\dfrac{1}{3}\cdot \dfrac{1}{2}=\dfrac{1}{6}.$

Answer: you need $\dfrac{1}{6}$ cup od butter.

Answer 2

Do 1/3 x 1/2 to get 1/6, or you could think, 1/3 divided by 2, which would equal 1/3 x 1/2
