Question

Select the correct combination of the mathematical signs that can be filled to balance the following equation.

24 ___ 6 ___ 3 ___ 4 ___ 10 ___ 6

• A. ÷, ×, =, +, +
• B. ÷, ×, +, =, +
• C. ÷, ×, -, =, ×
• D. +, =, ÷, ×, +

Answer 1

Answer:

B. ÷, ×, +, =, +

Solution: Given equation: 24 ___ 6 ___ 3 ___ 4 ___ 10 ___ 6 Substituting the signs and using BODMAS rule: 1) ÷, ×, =, +, + 24 ÷ 6 × 3 = 4 + 10 + 6 LHS: 24 ÷ 6 × 3 = 4 × 3 = 12 RHS: 4 + 10 + 6 = 20 LHS ≠ RHS 2) ÷, ×, +, =, + 24 ÷ 6 × 3 + 4 = 10 + 6 LHS: 24 ÷ 6 × 3 + 4 = 4 × 3 + 4 = 12 + 4 = 16 RHS: 10 + 6 = 16 LHS = RHS 3) ÷, ×, -, =, × 24 ÷ 6 × 3 - 4 = 10 × 6 LHS: 24 ÷ 6 × 3 - 4 = 4 × 3 - 4 = 12 - 4 = 8 RHS: 10 × 6 = 60 LHS ≠ RHS 4) +, =, ÷, ×, + 24 + 6 = 3 ÷ 4 × 10 + 6 LHS: 24 + 6 = 30 RHS: 3 ÷ 4 × 10 + 6 = 0.75 × 10 + 6 = 7.5 + 6 = 13.5 LHS ≠ RHS Hence, the correct answer is "÷, ×, +, =, +".
