Given equation: (14 * 9 * 6) * 15 * 8 Check the options Option 1: ×, =, ÷, - After interchanging the equation becomes; = (14 × 9 = 6) ÷ 15 - 8 = 126 is not equal to -7.5. Hence, option 1 is not the correct answer. |
|
Option 2: ×, -, ÷, = After interchanging the equation becomes; = (14 × 9 - 6) ÷ 15 = 8 = 8 Hence, option 2 is the correct answer. |
|
Option 3: -, ÷, ×, = After interchanging the equation becomes; = (14 - 9 ÷ 6) × 15 = 8 = 187.5 is not equal to 8. Hence, option 3 is not the correct answer. |
|
Option 4: ÷, -, =, × After interchanging the equation becomes; = (14 ÷ 9 - 6) = 15 × 8 = -4.44 is not equal to 120. Hence, option 4 is not the correct answer. |
