Question

A baker uses 1/8 of a cup of yeast every day. if he has 3/4 cups of yeast left, how many days can he bake before he runs out?

Answer 1

The baker uses 1/8 cup of yeast per day

He has 3/4 cups of yeast left

To calculate how many days he can bake before he runs out of yeast you can use cross multiplication:

1/8cup of yeast____1day

3/4cup of yeast____xdays

`\begin{gathered} (1)/((1)/(8))=(x)/((3)/(4)) \\ 8\cdot1=(4)/(3)\cdot x \\ (4)/(3)x=8 \\ x=8/(4)/(3) \\ x=8\cdot(3)/(4) \\ x=6 \end{gathered}`

The yeast will last for him to work 6 days
