Question

Two nails are 5/16 inch and 13/16 inch long. How much shorter is the 15/16 inch nail?

Answer 1

Ill assume you made a typo and meant 5/16 instead of 15/16. And the 5/16 inch nail is 8/16 inches shorter than the 13/16 one. Or you could simplify it to 1/2.

Answer 2

`(1)/(2) inch`

Explanation:

One of the nails is
`(5)/(16)` inch

The other nail is
`(13)/(16)` inch.

Since we are determining how much shorter the
`(5)/(16)` inch nail is, we simply find the difference in the length of the two nails.

`=(13)/(16)- (5)/(16)\\=(8)/(16)\\=(1)/(2) inch`
