A pancake recipe calls for 1/5 cup of sugar for every cup of flour.
Quantity A
Number of cups of sugar in 2 cups of sugar/flour mix
Quantity B
2/5 cups of sugar
The following are the answer choices
Select A if it's always greater.
Select B if it's always greater.
Select C if A & B are the same.
Select D if it can't be determined.
I know the answer but the explanation in the book sucks can someone please break down this problem in the most simple form and help me solve it step by step.
If we add $\frac{1}{5}$ of a cup of sugar to every cup of flour, then to get $\frac{2}{5}$ of a cup of sugar we'd need $2$ cups of flour. Then, the total mixture would be $2\frac{2}{5}$ cups containing $\frac{2}{5}$ of a cup of sugar. If we only took $2$ cups of that, we'd have less than $\frac{2}{5}$ cups of sugar.
