Select the correct combination of mathematical signs to sequentially replace the * signs and to balance the given equation.
(130 * 4) * 21 * 485 * (28 * 2)
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. ×, -, =, +, ÷.
Given equation: (130 * 4) * 21 * 485 * (28 * 2)
Option 1: ×, -, =, +, ÷
After interchanging the expression becomes:
= (130 × 4) - 21 = 485 + (28 ÷ 2)
= 520 - 21 = 485 + 14
= 499 = 499
Hence, option 1 is the correct answer.
