Answer:
[tex]\frac{5}{10}, \frac{4}{10}, \frac{1}{10}[/tex] are the numbers you need
Step-by-step explanation:
The least common denominator of those two numbers is 10.
[tex]\frac{1}{2} * \frac{5}{5} = \frac{5}{10} \\\\\frac{2}{5} * \frac{2}{2} = \frac{4}{10} \\\\\frac{5}{10} - \frac{4}{10} = \frac{1}{10}[/tex]
