Which of the following interchanges of signs would make the given equation correct?
5 - 4 ÷ 2 + 7 × 3 = 14
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. × and −.
Given equation: 5 - 4 ÷ 2 + 7 × 3 = 14
Option 1: × and −
After interchanging the expression becomes:
= 5 × 4 ÷ 2 + 7 - 3 = 14
= 5 × 2 + 7 - 3
= 10 + 7 - 3
= 17 - 3
= 14
Hence, Option 1 is the correct answer.
