Using the common denominator, what is an equivalent fractionitio \( \frac{3}{10} \) ?

To find an equivalent fraction using a common denominator, you can multiply both the numerator and the denominator of \( \frac{3}{10} \) by the same number. For example, if we want to use 20 as the common denominator, multiply both by 2 to get \( \frac{3 \times 2}{10 \times 2} = \frac{6}{20} \). So, \( \frac{6}{20} \) is an equivalent fraction for \( \frac{3}{10} \). Another fun way to visualize equivalent fractions is through pizza! Imagine cutting a pizza into 10 slices. If you take 3 slices, that's \( \frac{3}{10} \). Now, if you decide to cut that same pizza into 20 smaller slices, taking 6 of those would still represent the same amount of pizza, giving you \( \frac{6}{20} \) – the equivalent fraction!
