Question

What is the difference in length between 1 1/4 inch button and a 3/8 inch button

Answer 1

You have two buttons of different lengths.

First with length
`1(1)/(4)` in and second with length
`(3)/(8)` in. The first one is larger, then the difference in length between them is:

`1(1)/(2)-(3)/(8)=(3)/(2)-(3)/(8)=(3\cdot 4-3)/(8)=(12-3)/(8)=(9)/(8)=1(1)/(8)\ in.`

Answer:
`1(1)/(8)` in.
