Question

Two lions, Fluffy and Fireball, met at the zoo. Fluffy's tail is 1\dfrac{1}{3}1 3 1 ​ 1, start fraction, 1, divided by, 3, end fraction of a meter long. Fireball's tail is 1\dfrac{1}{4}1 4 1 ​ 1, start fraction, 1, divided by, 4, end fraction of a meter long. How much longer is Fluffy's tail than Fireball's tail?

Answer 1

Answer: Fluffy's tail is
`\frac1{12}` m longer than Fireball's tail.

Explanation:

Length of Fluffy's tail =
`1\frac13` m
`=\frac43` m

Length of Fireball's tail =
`1\frac14` m
`=\frac54` m

Difference = Length of Fluffy's tail - Length of Fireball's tail

`=\frac43-\frac54=(4*4-5*3)/(3*4)\\\\=(16-15)/(12)\\\\=\frac1{12}`

Hence, Fluffy's tail is
`\frac1{12}` m longer than Fireball's tail.
