Question

There is 1/4 ounce of yeast in every 2 1/4 teaspoons of yeast. A recipe for bread calls for 2 teaspoons of yeast. How many ounces of yeast are needed for this recipe?

Answer 1

1/4 ounce per 1/2 teaspoon
2 teaspoons--> 1 ounce

Answer 2

`(2)/(9)` ounces of yeast are needed for this recipe

Explanation:

`2(1)/(4)`teaspoons of yeast requires ounces of yeast =
`(1)/(4)`

`(9)/(4)`teaspoons of yeast requires ounces of yeast =
`(1)/(4)`

1 teaspoons of yeast requires ounces of yeast =
`((1)/(4))/((9)/(4))`

2 teaspoons of yeast requires ounces of yeast =
`((1)/(4))/((9)/(4)) * 2`

2 teaspoons of yeast requires ounces of yeast =
`(2)/(9)`

Hence
`(2)/(9)` ounces of yeast are needed for this recipe
