Question

a new long life tire has a tread depth of 1/4 inches, instead of the more typical 5/32 inches. how much deeper is the new tire

Answer 1

You have to make both of them to lowest common denominator. In this case the lowest common denominator is 16. So multiply 1/4 × 4 and devide 5/32 by 2. Then it is 4/16 and 2.5/16. Now it is easier to compare. I hope you understand what I mean, and that I was correct ☺

Answer 2

`(3)/(32)` inches deeper is the new tire.

Explanation:

Given : A new long life tire has a tread depth of
`(1)/(4)` inches, instead of the more typical
`(5)/(32)` inches.

To find : How much deeper is the new tire ?

Solution :

The difference in depth is found by the difference in the measurements.

A new long life tire has a tread depth of
`(1)/(4)` inches.

The more typical has
`(5)/(32)` inches.

So, The difference in the tire is

`d=(1)/(4)-(5)/(32)`

Take the least common denominator,

`d=(8-5)/(32)`

`d=(3)/(32)`

Therefore,
`(3)/(32)` inches deeper is the new tire.
