Select the correct combination of mathematical signs to sequentially replace the * signs and to balance the given equation.
19 * 5 * 5 * 220 * 2 * 10
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. ×, +, =, ÷, −.
Given equation: 19 * 5 * 5 * 220 * 2 * 10
Option 1: +, −, =, ×, ÷
After interchanging the expression becomes:
= 19 + 5 − 5 = 220 × 2 ÷ 10
= 19 + 5 − 5 = 44
= 19 is not equal to 44
Option 2: ×, +, =, ÷, −
After interchanging the expression becomes:
= 19 × 5 + 5 = 220 ÷ 2 −10
= 95 + 5 = 110 −10
= 100 = 100
As we have found our answer, there is no need to check further options.
Hence, ÷, ×, =, +, − is the correct answer.
