Question

Robyn uses 1/2 cup of blueberries to make each loaf of blueberry bread. Explain how many loaves of blueberry bread she can make with 2 1/2 cups of blueberry

Answer 1

Robyn will use
`2\frac {1}{2}` of blueberries to make 5 loaves of bread.

Explanation:

Note: It is always a good practice to bring the given quantity to one single unit and then multiply with the quantity that is asked for.

Robyn uses
`\frac {1}{2}` cup of blueberries to make 1 loaf of bread.

So she will use 1 cup of blueberries to make 2 loaves of bread.

Multiplying throughout by
`2\frac {1}{2}` we get that

She will use
`2\frac {1}{2}` cup of blueberries to make
`2* 2\frac {1}{2}` loaves of bread.

Now, we will convert mixed fraction to improper fraction.

So,
`2* 2\frac {1}{2}=2* \left( 2+\frac {1}{2}\right)`
`=2* \frac {5}{2} = 5`.

Therefore, Robyn will use
`2\frac {1}{2}` cup of blueberries to make 5 loaves of bread.
