Write \( \frac{15}{20} \) in lowest terms.

To reduce \( \frac{15}{20} \) to its lowest terms, you need to find the greatest common divisor (GCD) of the numerator and denominator. The GCD of 15 and 20 is 5. Dividing both the numerator and the denominator by 5 gives you \( \frac{15 ÷ 5}{20 ÷ 5} = \frac{3}{4} \). So, in lowest terms, \( \frac{15}{20} \) is \( \frac{3}{4} \). A little math magic here: understanding fractions can be a handy skill in cooking! If a recipe calls for \( \frac{15}{20} \) of a cup of sugar and you want to simplify it, knowing it’s the same as \( \frac{3}{4} \) of a cup makes measuring easier. Just think of that perfect slice of cake, and remember that simplifying fractions can lead to even sweeter results in the kitchen!
