Calculation:

To solve the equation 7/12 - 2/5, we can first find a common denominator for the fractions. The common denominator for 12 and 5 is 60.

Converting the fractions to have a denominator of 60: - 7/12 becomes 35/60 (multiplied the numerator and denominator by 5) - 2/5 becomes 24/60 (multiplied the numerator and denominator by 12)

Now, the equation becomes: 35/60 - 24/60

Subtracting the numerators: 35 - 24 = 11

So, 7/12 - 2/5 = 11/60.

Next, to find the product of 2 7/9 and 18/25: First, convert the mixed number 2 7/9 to an improper fraction: - 2 * 9 = 18 - 18 + 7 = 25 So, 2 7/9 as an improper fraction is 25/9.

Now, multiply 25/9 by 18/25: (25/9) * (18/25)

The common factor of 25 cancels out: (25 * 18) / (9 * 1) = 450 / 9 = 50

So, 2 7/9 * 18/25 = 50.

Therefore, 7/12 - 2/5 = 11/60 and 2 7/9 * 18/25 = 50.
