Answer:
3 and a half cups of flour
Step-by-step explanation:
Solve using proportions:
milk to flour ratios
[tex]\frac{1\frac{1}{3} }{1} = \frac{4 \frac{2}{3} }{y}\\[/tex]
Find the scale factor for the increase of milk by dividing the second amount by the first amount.
Divide four and two thirds by one and one thirds.
[tex]4\frac{2}{3} / 1\frac{1}{3}\\\frac{14}{3} / \frac{4}{3} = \frac{14}{3} X \frac{3}{4}\\= \frac{42}{12} = \frac{7}{2} = 3.5[/tex]
The scale factor is 3.5.
Multiply the amount of flour by the scale factor to get the second amount.
Multiply one by 3.5.
1 X 3.5 = 3.5
3.5 = 3 1/2
We need 3 and a half cups of flour when there are four and two thirds cups of milk.
