Answer 3

Let's substitute the values of а and б into the equation:

1 - (1 - (7/15)) - (1 - (8/15))

First, let's simplify the innermost parentheses:

1 - (1 - 7/15) - (1 - 8/15)

Next, let's simplify the parentheses:

1 - (8/15) - (7/15)

Now, we can combine the fractions:

1 - 8/15 - 7/15

To subtract fractions, we need a common denominator, which in this case is 15. So let's convert the fractions:

1 - (8/15) - (7/15) = 15/15 - 8/15 - 7/15

Now we can subtract the fractions:

15/15 - 8/15 - 7/15 = (15 - 8 - 7)/15 = 0/15 = 0

Therefore, the equation 1 - (1 - а) - (1 - б) with а = 7/15 and б = 8/15 equals 0.
