Select the correct combination of mathematical signs to sequentially replace the * signs and to balance the given equation.
64 * 140 * 2 * 4 * 10
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. =, ÷, +, −.
Given equation: 64 * 140 * 2 * 4 * 10
Option 1: =, ÷, +, −
After interchanging the expression becomes:
= 64 = 140 ÷ 2 + 4 − 10
= 64 = 70 + 4 − 10
= 64 = 74 − 10
= 64 is equal to 64.
As we have found our answer, there is no need to check further options.
Hence, option 1 is the correct answer.
