Answer 3

To solve the expression, let's break it down step by step:

First, let's simplify the multiplication: 2 2/5 × 5/6

To multiply mixed numbers, you need to convert them to improper fractions: 2 2/5 = (5 × 2 + 2) / 5 = 12/5

Now, multiply the fractions: (12/5) × (5/6) = (12 × 5) / (5 × 6) = 60/30

Next, let's simplify the second multiplication: 3/4 × 1 2/3

Convert the mixed number to an improper fraction: 1 2/3 = (3 × 1 + 2) / 3 = 5/3

Multiply the fractions: (3/4) × (5/3) = (3 × 5) / (4 × 3) = 15/12

Now, let's subtract the two results: 60/30 - 15/12

To subtract fractions, you need to have a common denominator. In this case, the least common multiple of 30 and 12 is 60. Let's convert the fractions to have a denominator of 60:

60/30 = (60 × 2) / (30 × 2) = 120/60 15/12 = (15 × 5) / (12 × 5) = 75/60

Now, subtract the fractions: 120/60 - 75/60 = (120 - 75) / 60 = 45/60

The fraction 45/60 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 15:

45/60 = (45 ÷ 15) / (60 ÷ 15) = 3/4

Therefore, the final result is 3/4.
