Question

3/4 * 1 1/4 * 7 1/2 *2 1/4 : 7 1/2

Answer 1

$\frac{3}{4}$ ×  $\frac{11}{4}$ ×  $\frac{71}{2}$ ×  $\frac{21}{4}$ ÷  $\frac{71}{2}$
2 $\frac{1}{16}$ × 186  $\frac{3}{8}$ ÷  $\frac{71}{2}$
384  $\frac{51}{128}$ ÷ $\frac{71}{2}$ = 10  $\frac{53}{64}$

Answer 2

To simplify the expression, we can cancel out common factors in the numerator and denominator:

3/4 * 1 1/4 * 7 1/2 * 2 1/4 : 7 1/2

= (3/4) * (5/4) * (15/2) * (9/4) : (15/2)

= (3 * 5 * 15 * 9) / (4 * 4 * 2 * 15)

= 2025 / 480

= 33/8 or 4 1/8
