Answer 2

To calculate the expression, follow these steps:

Step 1: Find a common denominator for the fractions involved. The least common multiple (LCM) of 40 and 30 is 120.

Step 2: Convert both fractions to have a denominator of 120.

Step 3: Perform the subtraction.

Step 4: Multiply the result by 9/118.

Let's do the calculations:

Step 1: LCM of 40 and 30 = 120

Step 2: (19/40) * (3/3) = 57/120 (29/30) * (4/4) = 116/120

Step 3: Subtract: (57/120) - (116/120) = (57 - 116) / 120 = -59/120

Step 4: Multiply: (-59/120) * (9/118) = (-59 * 9) / (120 * 118) = -531 / 14160

The final result is -531/14160.
