A recipe for sugar cookies requires 2 cups of flour for every 2/3 cup of sugar.
To Find: at this rate how many cups of sugar should we use if 5 cups of flour is included.
For recipe of Sugar cookie =
Sugar required for cups of flour= [tex]\dfrac{2}{3}\ cup[/tex]
Sugar required for cup of flour= [tex]\dfrac{2}{3}\times \dfrac{1}{2}=\dfrac{1}{3}[/tex]
Now,
If 5 cups of flour is included
cups of sugar required
[tex]=5\times Number \ of \ sugar\ cups\ required\ for\ 1\ cup\ of\ flour\\[/tex]
[tex]=5\times \dfrac{1}{3}=\dfrac{5}{3}\ cups[/tex]
