Answer 2

To solve the expression, let's break it down step by step:

1. 43/10 • 3: Multiplying a fraction by a whole number can be done by multiplying the numerator with the whole number. So, we have: (43/10) • 3 = (43 • 3) / 10 = 129/10

2. 3/14 - 13/14 • 4: First, let's simplify the multiplication part: 13/14 • 4 = (13 • 4) / 14 = 52/14 Now, we can subtract the fractions: 3/14 - 52/14 = (3 - 52) / 14 = -49/14

3. Finally, we need to multiply the result from step 1 by the result from step 2: (129/10) • (-49/14) = (129 • -49) / (10 • 14) = -6309/140

Therefore, the final result of the expression 43/10 • 3 - 13/14 • 4 3/10 is -6309/140.
