4 1/2 = [?]/[?]

1 answer

To express \(4 \frac{1}{2}\) as a fraction, we can convert the mixed number to an improper fraction.

  1. First, convert \(4\) to a fraction with the same denominator as the fractional part. Since \(\frac{1}{2}\) has a denominator of \(2\), we can write \(4\) as \(\frac{4 \times 2}{2} = \frac{8}{2}\).

  2. Now, add the fractional part: \[ 4 \frac{1}{2} = \frac{8}{2} + \frac{1}{2} = \frac{8 + 1}{2} = \frac{9}{2}. \]

So, \(4 \frac{1}{2} = \frac{9}{2}\). Therefore, you can express it as:

\[ \frac{9}{2} = [?]/[?] \rightarrow \text{where } ? = 9 \text{ and } ? = 2. \]
