Sugar 8

Heather has 2 cups of powdered sugar. She sprinkles 3/5 of the sugar onto a plate of brownies and sprinkles the rest into a plate of lemon cookies. How much sugar does Heather sprinkle on the brownies? How much sugar does Heather sprinkle on the lemon cookies?

Correct answer:

a =  6/5 = 1 ¹⁄₅
l =  4/5

Step-by-step explanation:

$$\begin{gathered} s=2 \\ a=s\cdot \frac{3}{5}=2\cdot \frac{3}{5}=\frac{2\cdot 3}{5}=\frac{6}{5}=1\frac{1}{5}=1.2 \end{gathered}$$

$l=s-a=2-\frac{6}{5}=\frac{2\cdot 5}{5}-\frac{6}{5}=\frac{10}{5}-\frac{6}{5}=\frac{10-6}{5}=\frac{4}{5}=0.8$
