Answer 2

$8 - 4 \frac{1}{2} - 2 \frac{1}{4} \\= 8 - (4 +\frac{1}{2} ) - (2 +\frac{1}{4}) \\= 8 - 4 -\frac{1}{2} - 2 -\frac{1}{4} \\= 8 - 4 - 2 - \frac{1}{2} - \frac{1}{4} \\=2 - \frac{1}{2} - \frac{1}{4} \\= \frac{8-2-1}{4}\\= \frac{5}{4} \\=1 \frac{1}{4}$

Therefore.,

$\red{8 - 4 \frac{1}{2} - 2 \frac{1}{4}} \green {= 1 \frac{1}{4}}$
