Answer 1

Given the expression

`-24\cdot(1)/(2)+16.15-4`

The result for this expression is 0.15

An equivalent expression will be one that has the same result.

First expression:

`24\cdot(1)/(2)-16.15+4=-0.15`

This expression has a similar result but with negative sign so is not equivalent.

Second expression:

`16.15-28.5=-12.35`

This expression is not equivalent.

Third expression:

`-28.5+16.15=-12.35`

This expression is not equivalent.

Fourth expression

`-20\cdot(1)/(2)+16.5=6.5`

This expression is not equivalent.

Fifth expression

`12.15-24\cdot(1)/(2)=0.15`

This expression is equivalent.

The only expression that is equivalent to the given one is the 5th.
