Answer 3

To solve the expression (1-6/13) + (1-7/13) - (1-4/14), follow these steps:

Step 1: Perform the operations within parentheses first. Step 2: Perform addition and subtraction from left to right.

Let's solve it step-by-step:

Step 1: (1 - 6/13) + (1 - 7/13) - (1 - 4/14)

Step 2: Now, we'll calculate the values within each set of parentheses:

(1 - 6/13) = (13/13 - 6/13) = 7/13 (1 - 7/13) = (13/13 - 7/13) = 6/13 (1 - 4/14) = (14/14 - 4/14) = 10/14 = 5/7

Step 3: Substitute the calculated values back into the original expression:

(7/13) + (6/13) - (5/7)

Step 4: To add and subtract fractions with different denominators, we need to find a common denominator. In this case, the common denominator for 13 and 7 is 91.

Converting the fractions to have a common denominator:

(7/13) + (6/13)(7/7) - (5/7)(13/13) = (7/13) + (42/91) - (65/91)

Step 5: Now that all fractions have the same denominator, we can add and subtract them:

(7/13) + (42/91) - (65/91) = (7*7 + 42 - 65) / 91 = (49 - 23) / 91 = 26 / 91

So, the simplified value of the expression is 26/91.
