Select the correct combination of mathematical signs to replace the * signs and to balance the given equation.
67 * 88 * 8 * 14 * 3 * 19 * 17
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. +, ÷, −, ×, −, =.
The given equation is:
67 * 88 * 8 * 14 * 3 * 19 * 17
To balance the given equation, by checking the options:
1. −, ×, =, −, ÷, +
67 − 88 × 8 = 14 − 3 ÷ 19 + 17
⇒ 67 − 704 = 30.8421
⇒ -637 = 30.8421
-637 is not equal to 30.8421.
2. +, ÷, −, ×, −, =
67 + 88 ÷ 8 − 14 × 3 − 19 = 17
⇒ 67 + 11 − 42 − 19 = 17
⇒ 78 − 42 − 19 = 17
⇒ 17 = 17
17 is equal to 17.
Hence, Option 2 is the correct answer.
