Explanation:

The complete question is

Dianna made several loaves of bread yesterday. Each loaf required 2 2/3 cups of flour. All together, she used 13 1/3 cups of flour. How many loaves did Dianna make?

step 1

Convert mixed number to an improper fraction

`2(2)/(3)\ cups=(2*3+2)/(3)=(8)/(3)\ cups`

`13(1)/(3)\ cups=(13*3+1)/(3)=(40)/(3)\ cups`

step 2

Find out how many loaves did Dianna make , if she used 40/3 cups of flour

we know that

Each loaf required 8/3 cups of flour

Using proportion

Let

x ----> the number of loaves of bread

`(1)/((8/3))(loaf)/(cups\ of\ flour)=(x)/((40/3))(loaves)/(cups\ of\ flour)\\\\x=(40/3)/(8/3)\\\\x=40/8\\\\x=5\ loaves`
