Please what is the answer?

Fluffy's Tail is longer than fireball's Tail by 1/12m.

Step-by-step explanation:

Given that fluffy's tail is 1 1/3m long and fireball's tail is 1 1/4m long

To find the difference in the length of the two tails, we subtract the length of fireball's tail from the length of fluffy's tail.

First, convert to proper fraction

Fluffy's tail is 1 1/3 = 4/3m

Fireball's tail is 1 1/4 = 5/4m

Then we find the Difference

= 4/3 - 5/4

=16 - 15 /12

=1/12

Fluffy's Tail is longer than fireball's Tail by 1/12m long

I hope this helps.
