Which of the following interchanges of signs would make the given equation correct?
110 ÷ 20 + 5 × 13 – 9 = 153
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. ÷ and +.
Given equation: 110 ÷ 20 + 5 × 13 – 9 = 153
After interchanging the expression becomes:
= 110 + 20 ÷ 5 × 13 – 9 = 153
= 110 + 4 × 13 – 9
= 110 + 52 – 9
= 162 - 9
= 153 = 153
