Answer 2

To subtract the given mixed numbers, you can follow these steps:

1. Subtract the whole numbers separately.
2. Subtract the fractions separately.

Let's do the calculation step by step:

1. Subtract the whole numbers: 4 - (8 - 8) = 4 - 0 = 4

2. Subtract the fractions: 26/57 - (19/57 - 45/57)

Now, we need to subtract the fractions in the parentheses. To do this, find a common denominator, which is 57 in this case:

26/57 - (19/57 - 45/57)

Now, subtract the fractions:

26/57 - (19/57 - 45/57) = 26/57 - (-26/57)

To subtract the fractions, change the subtraction into addition by changing the sign of the second fraction:

26/57 + 26/57

Now, add the fractions:

(26 + 26)/57 = 52/57

So, the result is:

4 52/57
