Which is greater

Question

A 1/10

B 0.12

C 13/100

D 1.1/10

Answer 1

Let's convert everything to have the same denominator. You can also make everything decimal, but I feel like bucking trends right now.

1/10 ⇒ 10/100 (multiply by 10/10)

0.12 ⇒ 12/100 (standard conversion at 2 decimals)
13/100  (no need to change)
1.1/10 ⇒ 11/100 (multiply by 10/10)

 

Now look at them and ask yourself which one has the highest numerator.
