Answer: 22
Step-by-step explanation:
(1 × 3) + [2 × 3 [tex]\frac{1}{2}[/tex]] + [1 × 3 [tex]\frac{3}{4}[/tex] [1 × 4 [tex]\frac{1}{4}[/tex]] + [3 × [tex]\frac{3}{4}[/tex]] + [3 × 5 [tex]\frac{1}{4}[/tex]]
= 3 + [2 × [tex]\frac{3}{2}[/tex]] + [1 × [tex]\frac{9}{4}[/tex]] + [1 × [tex]\frac{4}{4}[/tex]] + [3 × [tex]\frac{12}{4}[/tex]] + [3 × [tex]\frac{5}{4}[/tex]]
= 3 + [tex]\frac{6}{2}[/tex] + [tex]\frac{9}{4}[/tex] + [tex]\frac{4}{4}[/tex] (equal to 1) + [tex]\frac{36}{4}[/tex] + [tex]\frac{15}{4}[/tex]
= 3 + 3 + [tex]\frac{9}{4}[/tex] + 1 + 9 + [tex]\frac{15}{4}[/tex]
= 16 + [tex]\frac{9+15}{4}[/tex]
= 16 + [tex]\frac{24}{4}[/tex]
= 16 + 6
= 22
