The correct Answer is:
To solve the expression \( 3 \frac{1}{3} \div 6 \frac{3}{7} \times 1 \frac{1}{2} \times \frac{22}{7} \), we will follow the order of operations (BODMAS/BIDMAS). ### Step 1: Convert Mixed Numbers to Improper Fractions First, we convert the mixed numbers into improper fractions. - \( 3 \frac{1}{3} = \frac{10}{3} \) (since \( 3 \times 3 + 1 = 10 \)) - \( 6 \frac{3}{7} = \frac{45}{7} \) (since \( 6 \times 7 + 3 = 45 \)) - \( 1 \frac{1}{2} = \frac{3}{2} \) (since \( 1 \times 2 + 1 = 3 \)) Now, we can rewrite the expression: \[ \frac{10}{3} \div \frac{45}{7} \times \frac{3}{2} \times \frac{22}{7} \] ### Step 2: Perform Division Next, we perform the division: \[ \frac{10}{3} \div \frac{45}{7} = \frac{10}{3} \times \frac{7}{45} = \frac{10 \times 7}{3 \times 45} = \frac{70}{135} \] ### Step 3: Simplify the Fraction Now, we simplify \( \frac{70}{135} \): - The GCD of 70 and 135 is 5. \[ \frac{70 \div 5}{135 \div 5} = \frac{14}{27} \] ### Step 4: Multiply by \( \frac{3}{2} \) Now we multiply by \( \frac{3}{2} \): \[ \frac{14}{27} \times \frac{3}{2} = \frac{14 \times 3}{27 \times 2} = \frac{42}{54} \] ### Step 5: Simplify the Result Next, we simplify \( \frac{42}{54} \): - The GCD of 42 and 54 is 6. \[ \frac{42 \div 6}{54 \div 6} = \frac{7}{9} \] ### Step 6: Multiply by \( \frac{22}{7} \) Finally, we multiply by \( \frac{22}{7} \): \[ \frac{7}{9} \times \frac{22}{7} = \frac{7 \times 22}{9 \times 7} = \frac{22}{9} \] ### Conclusion Thus, the final answer is: \[ \frac{22}{9} \]
