Answer 3

Sure, I can help you with that math expression. Let's solve it step by step:

Step 1: Evaluate the expression inside the parentheses (brackets): 11/14 - 1/6

Step 2: Find a common denominator for 14 and 6, which is 42.

Step 3: Convert the fractions to have a denominator of 42: (11/14)(3/3) - (1/6)(7/7) (33/42) - (7/42)

Step 4: Subtract the fractions: (33/42) - (7/42) = (33 - 7)/42 = 26/42

Step 5: Now multiply the result from step 4 by 7/39: (7/39) * (26/42)

Step 6: Simplify the fraction: To simplify the fraction, find the greatest common divisor (GCD) of the numerator (26) and the denominator (42). The GCD of 26 and 42 is 2.

Divide both the numerator and denominator by the GCD (2): (7/39) * (26/42) = (7/39) * (13/21) = (7 * 13) / (39 * 21) = 91 / 819

The final answer is 91/819.
