Question : Directions: Select the correct combination of mathematical signs to replace * signs and to balance the following equation. (9 * 8 * 7) * 13 * 5
Option 1: ×, =, ÷, −
Option 2: ×, −, ÷, =
Option 3: ÷, −, =, ×
Option 4: −, ÷, ×, =
Correct Answer: ×, −, ÷, =
Solution : Given: (9 * 8 * 7) * 13 * 5
Let's check the options – First option: ×, =, ÷, − 9 × 8 = 7 ÷ 13 – 5 9 × 8 = 7 ÷ 13 – 5 72 = 0.53 – 5 72 = – 4.47 L.H.S. ≠ R.H.S. Second option: ×, −, ÷, = (9 × 8 – 7) ÷ 13 = 5 L.H.S. = (9 × 8 – 7) ÷ 13 = (72 – 7) ÷ 13 = 65 ÷ 13 = 5 Third option: ÷, −, =, × (9 ÷ 8 – 7) = 13 × 5 L.H.S. = (9 ÷ 8 – 7) = (1.125 – 7) = – 5.875 R.H.S. = 13 × 5 = 65 – 5.875 ≠ 65 L.H.S. ≠ R.H.S. Fourth option: −, ÷, ×, = (9 – 8 ÷ 7) × 13 = 5 L.H.S. = (9 – 8 ÷ 7) × 13 = (9 – 1.143) × 13 = 7.857 × 13 = 102.141 ≠ 5 L.H.S. ≠ R.H.S.
So, only the second option satisfies the equation. Hence, the second option is correct.
