4) \( \frac{2}{3} \div \frac{3}{4}= \)

To divide fractions, you multiply the first fraction by the reciprocal of the second. So, \( \frac{2}{3} \div \frac{3}{4} \) becomes \( \frac{2}{3} \times \frac{4}{3} \). Multiply the numerators (2 * 4 = 8) and the denominators (3 * 3 = 9) to get \( \frac{8}{9} \). Voilà! Your answer is \( \frac{8}{9} \). This trick of flipping and multiplying can be a great time-saver in the kitchen too! If you're baking and need to adjust a recipe, say you have \( \frac{2}{3} \) of a cup of flour and want to divide it among \( \frac{3}{4} \) of a recipe, just use this method! It’s both practical and a great way to impress your friends with your math skills.
