Answer:
[tex]3\frac{1}{6}[/tex]
Step-by-step explanation:
Given : A baker needs cups of flour = [tex]4\frac{3}{4} =\frac{19}{4}[/tex]
Solution :
Since we are given that she uses 1 measuring scoop for cup of flour = [tex]1\frac{1}{2} =\frac{3}{2}[/tex]
She uses uses scoop for 1 cup of flour = [tex]\frac{1}{\frac{3}{2}}=\frac{2}{3}[/tex]
She uses scoops for [tex]\frac{19}{4}[/tex] cups of flour = [tex]\frac{2}{3}*\frac{19}{4}[/tex]
= [tex]\frac{19}{6}[/tex]
= [tex]3\frac{1}{6}[/tex]
Thus [tex]3\frac{1}{6}[/tex] scoops of flour must the baker use to have at least 4 3⁄4 cups.
