Which two signs should be interchanged to make the equation mathematically correct?
60 ÷ 3 × 20 − 15 + 12 = 6
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. ÷ and ×.
Given equation: 60 ÷ 3 × 20 − 15 + 12 = 6
Option 1: ÷ and ×
After interchanging the expression becomes:
= 60 × 3 ÷ 20 − 15 + 12 = 6
= 9 − 15 + 12
= 6 = 6
As we have found our answer, there is no need to check further options.
Hence, ÷ and × is the correct answer.
