[Homework Help] Simplify \(\frac{13}{100} \div \frac{11}{20}\). 1. \(\frac{13}{100} \div \frac{11}{20}\) 2. Convert the division to multiplication by taking the reciprocal of the second fraction: \[ \frac{13}{100} \times \frac{20}{11} \] 3. Multiply the numerators and denominators: \[ \frac{13 \times 20}{100 \times 11} = \frac{260}{1100} \] 4. Simplify the fraction by dividing both the numerator and denominator by their greatest common divisor (20): \[ \frac{260 \div 20}{1100 \div 20} = \frac{13}{55} \] So, \(\frac{13}{100} \div \frac{11}{20} = \frac{13}{55}\).
