In the equation given below, which 2 signs need to be interchanged so that it is balanced?
1 / 4 ÷ 1 /16 - 5 + 45 × 25 = 40
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. × and −.
Given equation: 1 / 4 ÷ 1 /16 - 5 + 45 × 25 = 40
Option 1: × and −
After interchanging the expression becomes:
= 1 / 4 ÷ 1 /16 × 5 + 45 - 25 = 40
= 4 × 5 + 45 - 25
= 20 + 45 - 25
= 65 - 25
= 40 = 40
As we have found our answer, there is no need to check further options.
Hence, × and − is the correct answer.
