Пошаговое объяснение:

Answer 2

1. To solve the equation 1 - 7/15, you need to find a common denominator for the fractions involved. In this case, the common denominator is 15.

To subtract fractions with the same denominator, you subtract the numerators and keep the denominator the same. Applying this to the equation, we have:

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

Therefore, 1 - 7/15 is equal to 8/15.

2. To solve the equation 5 3/8 - 2 5/8, you can start by subtracting the whole numbers and then subtract the fractions.

5 - 2 = 3 (subtracting the whole numbers)

Next, subtract the fractions. The denominators are already the same, so you can subtract the numerators directly.

3/8 - 5/8 = (3 - 5)/8 = -2/8

However, -2/8 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 2.

-2/8 = -1/4

Therefore, 5 3/8 - 2 5/8 is equal to -1/4.
