Answer:
She needs [tex]3\frac{1}{3}[/tex] cups of flour for each batch of cookies.
Step-by-step explanation:
A baker needs a total [tex]13\frac{1}{3}[/tex] cups of flour to make four batches of cookies.
We have to calculate how much flour she needs for each batch of cookies.
Let the flour needed for one batch be f, so the expression would be
f × 4 = [tex]13\frac{1}{3}[/tex]
First we convert mixed fraction to proper fraction.
f × 4 = [tex]\frac{40}{3}[/tex]
f = [tex]\frac{\frac{40}{3} }{4}[/tex]
= [tex]\frac{40}{3}[/tex] × [tex]\frac{1}{4}[/tex] = [tex]\frac{10}{3}[/tex]
Now we convert this proper fraction to mixed fraction.
[tex]\frac{10}{3}[/tex] = [tex]3\frac{1}{3}[/tex]
She needs [tex]3\frac{1}{3}[/tex] cups of flour for each batch of cookies.
