Given Equation: 22 + 11 × 22 - 2 ÷ 3 = 45 Check all the options: Option 1: + and ÷ After replacement the equation becomes; = 22 ÷ 11 × 22 - 2 + 3 = 45 is equal to 45. Hence, option 1 is the correct answer. |
|
Option 2: × and ÷ After replacement the equation becomes; = 22 + 11 ÷ 22 - 2 × 3 = 16.5 is not equal to 45. Hence, option 2 is not the correct answer. |
|
Option 3: - and × After replacement the equation becomes; = 22 + 11 - 22 × 2 ÷ 3 = 18.33 is not equal to 45. Hence, option 3 is not the correct answer. |
|
Option 4: - and ÷ After replacement the equation becomes; = 22 + 11 × 22 ÷ 2 - 3 = 140 is not equal to 45. Hence, option 4 is not the correct answer. |
