Which of the mathematical signs should be interchanged in the below equation to make it mathematically correct?
320 × 8 - 216 + 72 ÷ 5 = 184
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. × and ÷.
Given equation: 320 × 8 - 216 + 72 ÷ 5 = 184
Option 1: × and ÷
After interchanging the expression becomes:
= 320 ÷ 8 - 216 + 72 × 5 = 184
= 40 - 216 + 72 × 5
= 40 - 216 + 360
= 184 = 184
As we have found our answer, there is no need to check further options.
Hence, × and ÷ is the correct answer.
