Select the correct combination of mathematical signs to sequentially replace the * signs and to balance the given equation.
17 * 18 * 6 * 5 * 2 * 10
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3. i.e. +, ÷, –, ×, =.
Given equation: 17 * 18 * 6 * 5 * 2 * 10
Option 1: ×, –, ÷, +, =
After interchanging the expression becomes:
= 17 × 18 - 6 ÷ 5 + 2 = 10
= 306.8 is not equal to 10.
Option 2: ×, –, +, ÷, =
After interchanging the expression becomes:
= 17 × 18 - 6 + 5 ÷ 2 = 10
= 302.5 is not equal to 10.
Option 3: +, ÷, –, ×, =
After interchanging the expression becomes:
= 17 + 18 ÷ 6 - 5 × 2 = 10
= 10 is equal to 10.
Hence, option 3 is the correct answer.
