Question

Alan threw 8 grams of sugar into 32 grams of water. He made ______ grams of _______% sugar syrup.

Answer 1

He made 40 grams of 20% sugar syrup.

Explanation:

Alan threw 8 grams of sugar into 32 grams of water and got 8 + 32 = 40 grams of sugar syrup.

To determine the percent of sugar, note that

40 g - 100%,

8 g - x%,

then

`(40)/(8)=(100)/(x),\\\\40x=8\cdot 100,\\ \\40x=800,\\ \\x=20\%.`
