Answer 1

3, 4, and 5 are right.

The first two are wrong.

Answer 2

Two is C. You can multiply any number by the decimal equivalent of the percentage you are interested in (i.e. 40% if 50 is 0.4 * 50)

First one has me confused. Are they typed in correctly? 15% of 30 is 4.5

A. 15/30 = x/100
15/30 = 0.5, .5/100 = 0.005 Wrong

B. 15/100 = x/30
15/100 = 0.15, 0.15/30 = 0.005 Wrong

C. 15/100 30/x
15/100 = 0.15, 30/.15 = 200 Wrong

D. 30/100 = 15/x
30/100 = 0.3, 15 / 0.3 = 50 Wrong
