25 * 5 * 10 * 2 * 4 * 7
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3. i.e. ÷, +, –, ×, =.
Given equation: 25 * 5 * 10 * 2 * 4* 7
Option 3: ÷, +, –, ×, =
After interchanging the expression becomes:
25 ÷ 5 + 10 - 2 × 4 = 7
5 + 10 - 2 × 4 = 7
5 + 10 - 8 = 7
15 - 8 = 7
7 = 7
