Answer:
[tex]yes...his \: \: statement \: \: is \: \: correct[/tex]
Step-by-step explanation:
Sum of the given 2 numbers
[tex] - 1 \frac{3}{4} + 2 \frac{1}{2} \\ - \frac{7}{4} + \frac{5}{2} \\ - \frac{7}{4} + \frac{5 \times 2}{2 \times 2} \\ - \frac{7}{4} + \frac{10}{4} \\ \frac{ - 7 + 10}{4} \\ = \frac{3}{4} [/tex]
Difference between the given 2 numbers
[tex]2 \frac{1}{2} - 1\frac{3}{4} \\ \frac{5}{2} - \frac{7}{4} \\ \frac{5 \times 2}{2 \times 2} - \frac{7}{4} \\ \frac{10}{4 } - \frac{7}{4} \\ \frac{10 - 7}{4} \\ = \frac{3 }{4} [/tex]
So, It's clear to you that,
sum of -1 3/4 and 2 1/2 is the same as the difference between 2 1/2 and 1 3/4.
Hope this helps you.
