Answer 2

To make the equation true, you need to rearrange the numbers and add parentheses. Here's one possible way to do it:

14800 : (100 - 600 - 420) : (7 • 9) : 10 = 142

Let's solve it step by step:

1. First, inside the first set of parentheses, perform the subtraction: 14800 : (-920) : (7 • 9) : 10 = 142

2. Next, inside the second set of parentheses, perform the multiplication: 14800 : (-920) : 63 : 10 = 142

3. Now, perform the divisions: (14800 / -920) : 63 : 10 = 142

4. Continue performing the divisions: (-16.08695652173913) : 63 : 10 = 142

5. Finally, finish the divisions and find the result: -0.25555555555555554 = 142 (approximately)

Oops! It looks like I made a mistake, and the equation cannot be made true with the given numbers and operators. My apologies for the confusion.
