On the number line place a mark at -2 1/2
Minus means subtraction,
When you subtract a negative number you actually add the number:
-2 1/2 - (-1 3/4) = -2 1/2 + 1 3/4
When you add 1 3/4 to -2 1/2 the second dot would be placed at -3/4
But the difference between the two would be the 1 3/4 that you added.
The difference of the given fraction is Negative three-fourths
