Answer 2

To solve the expression, first, you need to find a common denominator for the fractions involved. In this case, the common denominator is 7 * 8 = 56. Then, you can perform the subtraction.

So, the expression becomes:

(5/7 + 2/7) - 6/8

Now, convert each fraction to have a denominator of 56:

(5/7) * (8/8) = 40/56 (2/7) * (8/8) = 16/56 (6/8) * (7/7) = 42/56

Now, the expression becomes:

(40/56 + 16/56) - 42/56

Add the fractions with the same denominator:

(40/56 + 16/56) = 56/56

Now, the expression becomes:

(56/56) - 42/56

Subtract the fractions:

(56/56) - (42/56) = 14/56

Finally, simplify the fraction:

14/56 = 1/4

So, the result of the expression is 1/4.
