Checking Option 1) ÷ and + 48 – 8 ÷ 4 + 5 × 6 = 32 After changing the sign, the equation is 48 – 8 + 4 ÷ 5 × 6 ≠ 32 (does not satisfy) Checking Option 2) × and + 48 – 8 ÷ 4 + 5 × 6 = 32 After changing the sign, the equation is 48 – 8 ÷ 4 × 5 + 6 ≠ 32 (does not satisfy) Checking Option 3) × and ÷ 48 – 8 ÷ 4 + 5 × 6 = 32 After changing the sign, the equation is 48 – 8 × 4 + 5 ÷ 6 ≠ 32 (does not satisfy) Checking Option 4) ÷ and – 48 – 8 ÷ 4 + 5 × 6 = 32 After changing the sign, the equation is 48 ÷ 8 – 4 + 5 × 6 = 32 6 - 4 + 30 = 32 2 + 30 = 32 (Option 4 satisfies) Hence, option 4 is the correct answer. |
