To convert the fraction \( \frac{15}{4} \) into an equivalent fraction in the form of \( \frac{?}{?} \), we can express \( 15 \) as a numerator and \( 4 \) as a denominator.
Since \( \frac{15}{4} \) is already a fraction, we can represent it as:
\[ \frac{15}{4} = \frac{15 \times n}{4 \times n} \]
where \( n \) is any non-zero number (to keep the value of the fraction the same). For simplicity, let's choose \( n = 1 \):
\[ \frac{15 \times 1}{4 \times 1} = \frac{15}{4} \]
If you want to use a different n, such as \( n = 2 \):
\[ \frac{15 \times 2}{4 \times 2} = \frac{30}{8} \]
Or if you choose \( n = 3 \):
\[ \frac{15 \times 3}{4 \times 3} = \frac{45}{12} \]
You can create many equivalent fractions based on your choice of \( n \).
Therefore, \( \frac{15}{4} \) can be expressed as:
\[ \frac{15}{4} = \frac{30}{8} \text{ or } \frac{45}{12} \text{ or any equivalent fraction.} \]
