Answer 2

To calculate the expression (2 1/3 - 3 3/8) * 4 4/5 + 2 4/9, we'll follow these steps:

Step 1: Convert mixed numbers to improper fractions. Step 2: Perform the subtraction operation. Step 3: Perform the multiplication operation. Step 4: Perform the addition operation.

Let's start:

Step 1: Convert mixed numbers to improper fractions. 2 1/3 = (2 * 3 + 1) / 3 = 7/3 3 3/8 = (3 * 8 + 3) / 8 = 27/8 4 4/5 = (4 * 5 + 4) / 5 = 24/5 2 4/9 = (2 * 9 + 4) / 9 = 22/9

Step 2: Perform the subtraction operation. (7/3 - 27/8)

To subtract fractions, we need to find a common denominator. The common denominator for 3 and 8 is 24.

(7/3) * (8/8) = 56/24 (27/8) * (3/3) = 81/24

Now we can perform the subtraction:

(56/24 - 81/24) = (-25/24)

Step 3: Perform the multiplication operation. ((-25/24) * (24/5))

The fraction (-25/24) multiplied by (24/5) will result in:

((-25 * 24) / (24 * 5)) = (-600 / 120) = (-5)

Step 4: Perform the addition operation. ((-5) + (22/9))

To add these fractions, we need to find a common denominator. The common denominator for -5 and 9 is 9.

(-5) = (-5 * 9/9) = (-45/9) (22/9)

Now we can perform the addition:

((-45/9) + (22/9)) = (-23/9)

The final result of the expression is -23/9.
