Answer 2

=====================================

Answer 3

To solve the fraction 1 5/7 - 4/5, we need to first convert the mixed number 1 5/7 into an improper fraction.

1 5/7 can be written as (7 * 1 + 5)/7, which is equal to 12/7.

Now, we can rewrite the equation as:

12/7 - 4/5

To subtract fractions, we need to find a common denominator. In this case, the least common multiple (LCM) of 7 and 5 is 35.

Now, let's convert the fractions so that they have a common denominator of 35:

(12/7) * (5/5) - (4/5) * (7/7) = 60/35 - 28/35

Subtracting the fractions:

(60 - 28)/35 = 32/35

Therefore, the solution to the fraction 1 5/7 - 4/5 is 32/35.
