D. 9/1
[tex](2 \frac{1}{4} + 1 \frac{3}{6} ) \times 2 \frac{2}{5} [/tex]
[tex] = (2 + 1) + ( \frac{1}{4} + \frac{3}{6} )) \times \frac{12}{5} [/tex]
[tex] = (3 + \frac{3}{4} ) \times \frac{12}{5} [/tex]
[tex] = 3 \frac{3}{4} \times \frac{12}{5} [/tex]
[tex] = \frac{15}{4} \times \frac{12}{5} [/tex]
[tex] = 3 \times 3[/tex]
[tex] = 9[/tex]
(2 1/4 + 1 3/6) × 2 2/5
= (9/4 + 9/6) × 12/5
= (27/12 + 18/12) × 12/5
= 45/12 × 12/5
= 540/60
= 9 ✔️
