Answer 3

To solve the expression, let's follow the order of operations (PEMDAS/BODMAS):

1. Parentheses/Brackets
2. Exponents/Orders
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

Now, let's simplify the expression step by step:

Step 1: Simplify the fractions first.

• 3 1/3 can be written as an improper fraction: (3 * 3 + 1) / 3 = 10/3
• 1 3/9 can be simplified to 1 1/3, and then converted to an improper fraction: (1 * 3 + 3) / 9 = 6/9 = 2/3
• 4 5/4 can be written as an improper fraction: (4 * 4 + 5) / 4 = 21/4

Now the expression becomes: 10/3 + 2/3 × 3 - 21/4

Step 2: Perform multiplication and division from left to right.

• 2/3 × 3 = (2 * 3) / 3 = 6/3 = 2

Now the expression becomes: 10/3 + 2 - 21/4

Step 3: Perform addition and subtraction from left to right.

• 10/3 + 2 = (10 + 6) / 3 = 16/3
• 16/3 - 21/4 = (16 * 4 - 21 * 3) / (3 * 4) = (64 - 63) / 12 = 1 / 12

The final result of the expression is 1/12.
