Question

b. 30
c. 300

2. 35% of 70 is _____.

a. 24.5
b. 50
c. 245

3. 90 is 50% of what number?

a. 45
b. 120
c. 180

Answer 1

The answers are:

1. A) 3

2. A) 24.5

3. C) 180

In order to find this, we need to multiply the first two together.

1.

15% * 20

.15 * 20

2.

35% * 70

.35 * 70

The last problem is a little different. Since the decimal comes second, you need to divide instead of multiply.

90/50%

90/.50
