(18 ÷ 9) + 9 × 8 = 24

A+, ÷

B+, ×

C18, 8

D×, ÷

Answer:

A. +, ÷

Read Explanation:

Solution: 1) +, ÷ Given equation: (18 ÷ 9) + 9 × 8 = 24 After interchanging signs, we get: (18 + 9) ÷ 9 × 8 = 24 => 27 ÷ 9 × 8 = 24 => 3 × 8 = 24 => 24 = 24 2) +, × Given equation: (18 ÷ 9) + 9 × 8 = 24 After interchanging signs, we get: (18 ÷ 9) × 9 + 8 = 24 => 2 × 9 + 8 = 24 => 18 + 8 = 24 => 26 ≠ 24 3) 18, 8 Given equation: (18 ÷ 9) + 9 × 8 = 24 After interchanging numbers, we get: (8 ÷ 9) + 9 × 18 = 24 => 0.89 + 162 = 24 => 162.89 ≠ 24 4) ×, ÷ Given equation: (18 ÷ 9) + 9 × 8 = 24 After interchanging signs, we get: (18 × 9) + 9 ÷ 8 = 24 => 162 + 1.125 = 24 => 163.125 ≠ 24 Hence, ‘+, ÷ ’ is the correct answer.
