Answer:

Step-by-step explanation:

The given expression is

$5\frac{3}{4}+2\frac{1}{4} =7\frac{4}{8}=7\frac{1}{2}$

We will rewrite the expression

$\frac{23}{4}+\frac{9}{4} =\frac{60}{8}=7\frac{1}{2}$

When we add the fraction

$\frac{23+9}{4}$ = $\frac{32}{4}$ = 8

While Andre says the answer is $7\frac{1}{2}$

because Andre added the denominator where he has to make a common denominator that should be 4 instead of 8.

Andre made mistake in this step
