Which two signs should be interchanged to make the equation mathematically correct?
112 - 14 ÷ 40 + 8 × 12 = 64
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. ÷ and -.
Given equation: 112 - 14 ÷ 40 + 8 × 12 = 64
Option 1: ÷ and -
After interchanging the expression becomes:
= 112 ÷ 14 - 40 + 8 × 12 = 64
= 8 - 40 + 8 × 12
= 8 - 40 + 96
= 64 is equal to 64.
As we have found our answer, there is no need to check further options.
Hence, option 1 is the correct answer.
