To solve for \(\frac{1}{2}- \frac{1}{10}\) You first need to find a common denominator.
To do so, you need to make both denominators 10 by multiplying the top and bottom of \(\frac{1}{2}\) by 5
\(\frac{5}{10}- \frac{1}{10}\)=\(\frac{4}{10}\) Reduce by dividing both the top and bottom by 2
Your answer is \(\frac{2}{5}\)
