Answer 1

Answer: 22

Step-by-step explanation:

(1 × 3) + [2 × 3 $\frac{1}{2}$] + [1 × 3 $\frac{3}{4}$ [1 × 4 $\frac{1}{4}$] + [3 × $\frac{3}{4}$] + [3 × 5 $\frac{1}{4}$]

= 3 + [2 × $\frac{3}{2}$] + [1 × $\frac{9}{4}$] + [1 × $\frac{4}{4}$] + [3 × $\frac{12}{4}$] + [3 × $\frac{5}{4}$]

= 3 + $\frac{6}{2}$ +  $\frac{9}{4}$ +  $\frac{4}{4}$ (equal to 1) + $\frac{36}{4}$ + $\frac{15}{4}$

= 3 + 3 + $\frac{9}{4}$ + 1 + 9 + $\frac{15}{4}$

= 16 + $\frac{9+15}{4}$

= 16 + $\frac{24}{4}$

= 16 + 6

= 22
