Answer 3

To solve the expression, we first need to find the result of the subtraction inside the parentheses, and then multiply that by 3/5.

Step 1: Subtract (7/9 - 5/6) To subtract fractions, we need a common denominator. The least common multiple (LCM) of 9 and 6 is 18.

(7/9) - (5/6)

To convert both fractions to have a common denominator of 18:

(7/9) * (2/2) = 14/18 (5/6) * (3/3) = 15/18

Now, we can perform the subtraction:

(14/18) - (15/18) = -1/18

Step 2: Multiply the result by 3/5 Now, we multiply the result (-1/18) by 3/5:

(-1/18) * (3/5)

Multiply the numerators and denominators:

(-1 * 3) / (18 * 5) = -3 / 90

The fraction -3/90 can be simplified by dividing both the numerator and denominator by their greatest common divisor (GCD), which is 3:

(-3/3) / (90/3) = -1/30

So, the final result is -1/30.
