Select the correct combination of mathematical signs to replace the *...
Let's apply the options into the given equation by using the BODMAS rule
BODMAS rule is Bracket of Division Multiplication Addition Subtraction.
67 * 88 * 8 * 14 * 3 * 19 * 17
Applying option 1) -, ×, =, −, ÷, +
67 - 88 × 8 = 14 - 3 ÷ 19 + 17
67 - 88 × 8 = 14 - 0.15 + 17
67 - 704 = 14 - 0.15 + 17
67 - 704 = 31 - 0.15
-637 = 30.85 Incorrect
Applying option 2)+, ÷, -, ×, -, =
67 + 88 ÷ 8 - 14 × 3 - 19 = 17
67 + 11 - 14 × 3 - 19 = 17
67 + 11 - 42 - 19 = 17
78 - 42 - 19 = 17
78 - 61 = 17
17 = 17 Correct
Applying option 3) -, ÷, ×, +, =, -
67 - 88 ÷ 8 × 14 + 3 = 19 - 17
67 - 11 × 14 + 3 = 19 - 17
67 - 154 + 3 = 19 - 17
70 - 154 = 19 - 17
-84 = 2 Incorrect
Applying option 4) +, -, =, ×, -, ×
67 + 88 - 8 = 14 × 3 - 19 × 17
67 + 88 - 8 = 42 - 323
155 - 8 = 42 - 323
147 = -281 Incorrect
Hence, the correct answer is "+, ÷, -, ×, -, ="

Select the correct combination of mathematical signs to replace the *...
Explanation:
To balance the given equation, we need to find the correct combination of mathematical signs to replace the * signs. Let's go through each option and evaluate them.

Option A: -, ×, =, −, ÷
This combination does not balance the equation. The signs - and ÷ are used twice, which means we have two subtractions and two divisions, but the equation only has one of each operation. Therefore, option A is incorrect.

Option B: , ÷, -, ×, -, =
This combination also does not balance the equation. The signs ÷ and - are used twice, which means we have two divisions and two subtractions, but the equation only has one of each operation. Therefore, option B is incorrect.

Option C: -, ÷, ×, , =, -
This combination balances the equation. Let's evaluate it step by step:

- First, we perform the division operation: 67 ÷ 88 = 0.7613636...
- Then, we perform the multiplication operation: 0.7613636... × 8 = 6.090909...
- Next, we perform the subtraction operation: 6.090909... - 14 = -7.909090...
- After that, we perform the multiplication operation: -7.909090... × 3 = -23.727272...
- Then, we perform the multiplication operation: -23.727272... × 19 = -450.90909...
- Finally, we perform the subtraction operation: -450.90909... - 17 = -467.90909...

Therefore, the correct combination of mathematical signs to balance the given equation is -, ÷, ×, , =, -.

Option D: , -, =, ×, -, ×
This combination does not balance the equation. The signs - and × are used twice, which means we have two subtractions and two multiplications, but the equation only has one of each operation. Therefore, option D is incorrect.

Therefore, the correct answer is option C: -, ÷, ×, , =, -.
