Given Equation: 32 * 14 * 18 * 9 * 12 * 22
Let's check each Option One by One:
Option 1) −, +, ÷, ×, =
Given: 32 * 14 * 18 * 9 * 12 * 22
After replacing the * signs we get;
32 - 14 + 18 ÷ 9 × 12 = 22
32 - 14 + 2 × 12 = 22
32 - 14 + 24 = 22
56 - 14 = 22
42 ≠ 22.
Option 2) +, −, ÷, ×, =
Given: 32 * 14 * 18 * 9 * 12 * 22
After replacing the * signs we get;
32 + 14 - 18 ÷ 9 × 12 = 22
32 + 14 - 2 × 12 = 22
32 + 14 - 24 = 22
46 - 24 = 22
22 = 22.
Option 3) ×, +, ÷, −, =
Given: 32 * 14 * 18 * 9 * 12 * 22
After replacing the * signs we get;
32 × 14 + 18 ÷ 9 - 12 = 22
32 × 14 + 2 - 12 = 22
448 + 2 - 12 = 22
450 - 12 = 22
438 ≠ 22.
Option 4) ÷, −, +, ×, =
Given: 32 * 14 * 18 * 9 * 12 * 22
After replacing the * signs we get;
32 ÷ 14 - 18 + 9 × 12 = 22
2.28 - 18 + 9 × 12 = 22
2.28 - 18 + 108 = 22
110.28 - 18 = 22
92.28 ≠ 22.
Hence, the correct answer is 'Option 2'.
