Question

Please help me out! <3

Answer 1

`-1 (3)/(4)`

Explanation:

Using this number line, we can plot our original number -
`(3)/(4)` (see picture attached)

Adding a negative is the same thing as subtracting - so we are subtracting
`2(1)/(2)` from
`(3)/(4)`.

To subtract this, we can break up
`2(1)/(2)` into 3 parts: 1, 1, and
`(1)/(2)`. We can subtract each of these from the current number and see where we land up. (again see picture)

We land up at
`-1 (3)/(4)`.

Hope this helped!
