Answer 3

To find the correct placement of the parentheses to obtain the result of 141, you can try different combinations and calculations. Here are the steps to solve it:

Given expression: 7 * 8 + 5 * 9 + 4 * 2

Step 1: Calculate the multiplication operations first: 7 * 8 + 5 * 9 + 4 * 2 = 56 + 45 + 8

Step 2: Now, perform the addition operations: = 101 + 8

Step 3: Finally, add the last two numbers: = 109

So, with the given expression, there is no way to place the parentheses to get the result of 141. The correct result is 109.
