Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Multiplication of Fractions
To multiply fractions, you multiply the numerators together and the denominators together. For example, multiplying 2/3 by 4/5 results in (2*4)/(3*5) = 8/15. This concept is essential for solving problems that involve multiplying fractions, as it simplifies the process and helps in finding the product efficiently.
