Which of the following interchange of numbers and signs would make the given equation correct?
10 − 4 ÷ 20 + 16 × 8 = 16
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 4 and 8, × and −.
Given equation: 10 − 4 ÷ 20 + 16 × 8 = 16
Option 2: 4 and 8, × and −
After interchanging the expression becomes:
10 × 8 ÷ 20 + 16 - 4 = 16
4 + 16 - 4 = 16
20 - 4 = 16
16 = 16
