Answer 2

To calculate the expression (6 19/14 - 1/8) - (1 - 5/7), you can follow these steps:

Step 1: Convert mixed numbers to improper fractions:

6 19/14 = 6 + 19/14 = (6*14 + 19)/14 = 83/14

Step 2: Perform the subtraction inside the parentheses:

(83/14 - 1/8) - (1 - 5/7)

Step 3: Find a common denominator for the fractions in each set of parentheses. The common denominator for 14 and 8 is 56.

So, rewrite the expression with a common denominator:

(83/14 * 4/4 - 1/8 * 7/7) - (1 * 8/8 - 5/7 * 8/8)

Step 4: Perform the operations within each set of parentheses:

(332/56 - 7/56) - (8/8 - 40/56)

Step 5: Continue simplifying:

(325/56) - (8/8 - 40/56)

Step 6: Perform the subtraction inside the second set of parentheses:

(325/56) - (0/56 - 40/56)

Step 7: Subtract the fractions:

(325/56) - (-40/56)

Step 8: Subtract the fractions by adding their negation:

(325/56) + (40/56)

Step 9: Add the fractions:

(325 + 40)/56 = 365/56

So, the result of the expression is 365/56.
