Answer 3

To solve this expression, we'll follow these steps:

1. Convert mixed fractions to improper fractions.
2. Perform the operations (multiplication and division) from left to right.

Given the expression:

$8 \frac{1}{3} \times 1 \frac{5}{7} \div 2 \frac{8}{21}$

Step 1: Convert mixed fractions to improper fractions.

$8 \frac{1}{3} = \frac{(8 \times 3) + 1}{3} = \frac{24 + 1}{3} = \frac{25}{3}$

$1 \frac{5}{7} = \frac{(1 \times 7) + 5}{7} = \frac{7 + 5}{7} = \frac{12}{7}$

$2 \frac{8}{21} = \frac{(2 \times 21) + 8}{21} = \frac{42 + 8}{21} = \frac{50}{21}$

The expression becomes:

$\frac{25}{3} \times \frac{12}{7} \div \frac{50}{21}$

Step 2: Perform the operations.

Multiply:

$\frac{25}{3} \times \frac{12}{7} = \frac{(25 \times 12)}{(3 \times 7)} = \frac{300}{21}$

Divide:

$\frac{300}{21} \div \frac{50}{21} = \frac{300}{21} \times \frac{21}{50} = \frac{300}{1050} = \frac{6}{21} = \frac{2}{7}$

So, the result of the expression is $\frac{2}{7}$.
