Answer 2

To calculate this expression, you can follow these steps:

Step 1: Convert mixed numbers to improper fractions.

• 2 2/5 = (5 * 2 + 2)/5 = 12/5
• 1 2/3 = (3 * 1 + 2)/3 = 5/3

So, the expression becomes:

(12/5 * 5/6) - (3/4 * 5/3)

Step 2: Multiply the fractions.

(12/5 * 5/6) = (12 * 5)/(5 * 6) = 60/30 = 2

(3/4 * 5/3) = (3 * 5)/(4 * 3) = 15/12 = 5/4

Step 3: Subtract the second result from the first result.

2 - (5/4)

Step 4: Subtract the fractions.

To subtract fractions, you need a common denominator. In this case, the common denominator is 4.

2 - (5/4) = (8/4) - (5/4)

Now subtract:

(8/4) - (5/4) = 3/4

So, the final result is 3/4.
