Given Equation: 15 + 15 × 15 - 15 ÷ 15 = 15 Check all the options: Option 1: - and ÷ After replacement the equation becomes; = 15 + 15 × 15 ÷ 15 - 15 = 15 is equal to 15. Hence, option 1 is the correct answer. |
|
Option 2: + and - After replacement the equation becomes; = 15 - 15 × 15 + 15 ÷ 15 = -209 is not equal to 15. Hence, option 2 is not the correct answer. |
|
Option 3: × and ÷ After replacement the equation becomes; = 15 + 15 ÷ 15 - 15 × 15 = -209 is not equal to 15. Hence, option 3 is not the correct answer. |
|
Option 4: + and × After replacement the equation becomes; = 15 × 15 + 15 - 15 ÷ 15 = 239 is not equal to 15. Hence, option 4 is not the correct answer. |
