Answer 2

To solve the expression, first, we need to calculate the absolute values and then perform the multiplication and addition. Here's how you can do it step by step:

1. Calculate the absolute values of -5/7 and -1/5: | -5/7 | = 5/7 | -1/5 | = 1/5

2. Now, substitute these absolute values back into the expression: (5/7) * 4/5 + (1/5) * 5/7

3. Next, perform the multiplications: (5/7) * (4/5) = (20/35) (1/5) * (5/7) = (5/35)

4. Finally, add the two results: (20/35) + (5/35) = (20/35 + 5/35) = 25/35

Now, you can simplify the fraction. The greatest common divisor of 25 and 35 is 5, so you can divide both the numerator and the denominator by 5 to simplify further:

(25/5) / (35/5) = 5/7

So, the simplified result of the expression | -5/7 | * 4/5 + | -1/5 | * 5/7 is 5/7.
