Question

A biologist measured one lizard that was 7/3 inches long and a second lizard that was 9/4 inches long. How much longer was the first lizard

Answer 1

One twelfth if an inch

Answer 2

First lizard is 1/12 inches longer than the second one.

Explanation:

From the given information it is clear that

Length of first lizard = 7/3 inches

Length of second lizard = 9/4 inches

We need to find difference in length of both lizards.

Difference in length = Length of first lizard - Length of second lizard

`Difference=(7)/(3)-(9)/(4)`

Make denominator common.

`Difference=(7* 4)/(3* 4)-(9* 3)/(4* 3)`

`Difference=(28)/(12)-(27)/(12)`

`Difference=(28-27)/(12)`

`Difference=(1)/(12)`

Therefore, first lizard is 1/12 inches longer than the second one.
