a, 2% of 150
b,

`b \: (3)/(2) \% \: of400`
c, 5% of 60
d, 6% of 50​

Answer 1

B)
`(3)/(2)` % of 400

Explanation:

A) 2% of 150 = 3

Start by expressing the percent as a decimal by dividing the percent by 100

2% -> 0.02

Next multiply the percent by the number given

0.02 * 150 = 3

B)
`(3)/(2)` % of 400 = 6

Start by expressing the percent as a decimal by dividing the percent by 100

3/2% -> 0.015

Next multiply the percent by the number given

0.015 * 400 = 6

C) 5% of 60

Start by expressing the percent as a decimal by dividing the percent by 100

5% -> 0.05

Next multiply the percent by the number given

0.05 * 60 = 3

D) 6% of 50

Start by expressing the percent as a decimal by dividing the percent by 100

6% -> 0.06

Next multiply the percent by the number given

0.06 * 50 = 3

After calculating all of the questions, we can see that the common product is 3, making B) the one that is not equal to the rest.
