Answer 2

To solve the expression, follow these steps:

Step 1: Convert mixed numbers to improper fractions.

• 2 3/7 can be written as (7 * 2 + 3) / 7 = 17/7
• (-6 4/7) can be written as (-7 * 6 - 4) / 7 = -46/7

Step 2: Perform the calculations within parentheses first.

• 43.2 * 17/7 = 184.8
• 43.2 * (-46/7) = -312.0

Step 3: Now perform the rest of the operations left to right.

• 43.2 • 17/7 - 43.2 • (-46/7) + 43.2 = 184.8 - (-312.0) + 43.2
• Remember that subtracting a negative number is the same as adding its positive counterpart.
• 184.8 + 312.0 + 43.2 = 540

So, the result of the expression is 540.
