A. + and −
B. ÷ and ×
C. − and ×
D. ÷ and −
A. + and −
B. ÷ and ×
C. − and ×
D. ÷ and −
Best answer
Answer: D. ÷ and −
Answer: (D) ÷ and −
Interchanging ÷ and − gives \(6 \times 3 - 12 \div 3 + 6 = 20\).
By BODMAS the left side is 20, which equals the right side.
None of the other interchanges makes the two sides equal.
