Question

100 is divisible by which of the following numbers 2,3,4,5,6,9 or 10?

A. 2,3,4, and 6
B. 2,4,5, and 10
C. 5, and 10
D. 2,4,6, and 10

Answer 1

The correct answer is B: 2,4,5, 10

We know that 100 is not divisible by 3 because 100/3 is 33.33 repeating, which is an irrational number.

We also know that 100 is not divisible by 6 because 100/6 is 16.66 repeating which is also an irrational number.

100/2=50 (rational)
100/4=25 (rational)
100/5=20 (rational)
100/10=20 (rational)
