To multiply two fractions, multiply the numerators together to get the new numerator and the denominators together to get the new denominator. Simplify the resulting fraction if possible.
Step 1: Multiply the Numerators
To multiply the fractions \(\frac{12}{13}\) and \(\frac{9}{8}\), first multiply the numerators:
\[ 12 \times 9 = 108 \]
Combine the results from Steps 1 and 2 to form the new fraction:
\[ \frac{108}{104} \]
Step 4: Simplify the Fraction
Simplify \(\frac{108}{104}\) by dividing both the numerator and the denominator by their greatest common divisor, which is 4:
\[ \frac{108 \div 4}{104 \div 4} = \frac{27}{26} \]
Final Answer
The product of \(\frac{12}{13}\) and \(\frac{9}{8}\) is \(\boxed{\frac{27}{26}}\).
