Simplify the following (4.5-11.25) -9/2

The answer is -11.25.

To solve this, let's first get everything to a decimal. This will make things easier.

(4.5 - 11.25) - 9/2

(4.5 - 11.25) - 4.5

Now because of the properties of addition and subtraction, we can remove the parenthesis.

4.5 - 11.25 - 4.5

And when we complete this operation, the 4.5 and -4.5 cancel, giving us just -11.25
