14. \( 1-\frac{4}{5}= \)

To solve \( 1 - \frac{4}{5} \), we can convert 1 into a fraction with the same denominator as \(\frac{4}{5}\). So, \( 1 = \frac{5}{5} \). Now, we can subtract: \[ \frac{5}{5} - \frac{4}{5} = \frac{5-4}{5} = \frac{1}{5}. \] Thus, \( 1 - \frac{4}{5} = \frac{1}{5} \). Want a fun math fact? The fraction \(\frac{1}{5}\) is the decimal 0.2, which is the same as 20%! You could think of it as getting a 20% discount—who doesn't love a good deal, right? Now, let's talk about common pitfalls! A frequent mistake when subtracting fractions is forgetting to convert whole numbers into fractions with a matching denominator. Always ensure they maintain the same base before you crunch those numbers!
