Option 2: +, ×, ÷, -, = After replacement the equation becomes; =15 + 4 × 26 ÷ 2 - 7 = 66 =60 is not equal to 66. Hence, option 2 is not the correct answer. |
|
Option 3: ×, +, ÷, -, = After replacement the equation becomes; = 15 × 4 + 26 ÷ 2 - 7 = 66 = 66 Hence, option 3 is the correct answer. |
|
Option 4: ×, +, -, ÷, = After replacement the equation becomes; = 15 × 4 + 26 - 2 ÷ 7 = 66 = 85.714 is not equal to 66. Hence, option 4 is not the correct answer. |
