Answer 2

To solve this expression, you can follow these steps:

Step 1: Convert all mixed numbers into improper fractions.

• 3 1/4 = 13/4
• 1 3/5 = 8/5
• 4 4/9 = 40/9

Step 2: Perform the multiplication and division operations.

• Multiply the first two fractions: (13/4) * (8/5) = 104/20
• Divide the result by the third fraction: (104/20) / (40/9) = (104/20) * (9/40) = 234/800

Step 3: Simplify the fraction.

• 234/800 can be simplified by dividing both the numerator and denominator by their greatest common divisor (GCD), which is 2: 234 ÷ 2 = 117, 800 ÷ 2 = 400
• So, the simplified fraction is 117/400.

Therefore, the result of the expression 3 1/4 * 1 3/5 : 4 4/9 is 117/400.
