Select the correct combination of mathematical signs to sequentially replace the * signs and to balance the given equation.
7 * 10 * 280 * 2 * 10 * 80
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. ×, =, ÷, +, −
Given equation: 7 * 10 * 280 * 2 * 10 * 80
Option 1: ×, =, ÷, +, −
After interchanging the expression becomes:
⇒ 7 × 10 = 280 ÷ 2 + 10 − 80
⇒ 70 = 140 + 10 − 80
⇒ 70 = 150 − 80
⇒ 70 is equal to 70.
As we have found our answer, there is no need to check further options.
Hence, ×, =, ÷, +, − is the correct answer.
