58) \( \frac{2}{3} \times \frac{4}{5}= \)

To multiply the fractions \( \frac{2}{3} \) and \( \frac{4}{5} \), simply multiply the numerators together and the denominators together: \( \frac{2 \times 4}{3 \times 5} = \frac{8}{15} \). So, \( \frac{2}{3} \times \frac{4}{5} = \frac{8}{15} \). Now, let’s dive into something extra compelling! In ancient times, fractions were used as a way to represent divisions in trade and commerce. The Egyptians, for instance, had a unique method for dealing with fractions, primarily using unit fractions, which are fractions where the numerator is 1! It’s fascinating how the concept of fractions has evolved over thousands of years, making complex calculations easier for everyone! If you find yourself often multiplying fractions, a great tip is to simplify before you multiply. For example, if your fractions share common factors, cancel them out before calculating to make your life easier! Common mistakes include forgetting to simplify or not multiplying both the top (numerator) and bottom (denominator) correctly. Always double-check your work to avoid those pesky errors!
