Explanation:

Step1: Find a common denominator

The denominators are 10 and 5. The least common denominator is 10. Rewrite $\frac{2}{5}$ with denominator 10: $\frac{2\times2}{5\times2}=\frac{4}{10}$

Step2: Subtract the numerators

Now subtract the fractions: $\frac{9}{10}-\frac{4}{10}=\frac{9 - 4}{10}=\frac{5}{10}$

Step3: Simplify the fraction

Simplify $\frac{5}{10}$ by dividing numerator and denominator by 5: $\frac{5\div5}{10\div5}=\frac{1}{2}$

Answer:

$\frac{1}{2}$
