Question

Use your knowledge of fractions to re-write the recipe for Banana Bread. The card states that it serves 10 people. How much flour is required to make enough bread for 30 people? O 3/2 cups flour 4 %cups flour O 1/2 cups flour 3 cups flour w

Answer 1

The recipe ingredients are for 10 people and if we want to expand our recipe to serve 30 people we have to make some changes.

Firstly, we are expanding the number of serves by threefold; therefore, we must increase the ingredient amount by three as well.

Having that in mind, 1 1/2 cups of flour that went into 10 servings now for 30 servings become

`1(1)/(2)*\frac{30people}{10\text{people}}`

SInce 1 1/2 = 3 /2 the above becomes

`\begin{gathered} (3)/(2)*3 \\ =(9)/(2) \end{gathered}`

our answer, therefore, is 9/ 2 cups of flour but we need to convert this to a mixed number

`(9)/(2)=4(1)/(2)`

Hence, 4 1/2 cups of flour are required.
