Answer 2

To solve this expression, follow these steps:

Step 1: Add the fractions 2/7 and 3 1/2 to get a single mixed number.

2/7 + 3 1/2 = 2/7 + 7/2 (convert 3 1/2 to an improper fraction by multiplying the whole number by the denominator and adding the numerator) 2/7 + 7/2 = (4/14) + (49/14) = 53/14

Step 2: Now, you have the expression as (53/14) × 4 2/3.

Step 3: Convert the mixed number 4 2/3 to an improper fraction.

4 2/3 = 4 + 2/3 = (4 * 3/3) + 2/3 = 12/3 + 2/3 = 14/3

Step 4: Multiply the fractions.

(53/14) × (14/3)

Step 5: Simplify by canceling common factors between the numerators and denominators.

(53/14) × (14/3) = (53/1) × (1/3) = 53/3

So, the final result is 53/3. If you want to express it as a mixed number:

53/3 = 17 2/3
