Dahlia cooks with her mother's apple slices. They mixed flour, sugar, and butter in a ratio of 10:3:2. How many grams of sugar and butter did they put in half a kilogram of flour?

Correct answer:

c =  150 g
m =  100 g

Step-by-step explanation:

$$\begin{gathered} u:c:m=10:3:2 \\ u=0.5\text{kg}\to \text{g}=0.5\cdot 1000\text{g}=500\text{g} \\ u:c=10:3 \\ c=3\cdot u/10=3\cdot 500/10=150\text{g} \end{gathered}$$

$$\begin{gathered} c:m=3:2 \\ m=2\cdot c/3=2\cdot 150/3=100\text{g} \end{gathered}$$
