Options
- A16 + 5 – 10 × 4 ÷ 3 = 9
- B16 – 5 × 10 ÷ 4 + 3 = 12
- C16 + 5 ÷ 10 × 4 – 3 = 9
- D16 × 5 ÷ 10 ÷ 4 – 3 = 19
Correct answer
A. 16 + 5 – 10 × 4 ÷ 3 = 9
Step-by-step solution
From the first option, we get: 16 + 5 – 10 × 4 ÷ 3 = 9 ⇒ 16 × 5 ÷ 10 + 4 – 3 = 9 ⇒ 16 × 1 + 4 – 3 = 9 2 ⇒ 8 + 4 – 3 = 9 ⇒ 12 – 3 = 9. Hence, the option A is correct.
