Explanation:

Question 9

Step1: Identify fractions

Jon's fraction: $\frac{1}{2}$, Andrea's fraction: $\frac{2}{5}$

Step2: Subtract fractions

Find common denominator (10): $\frac{1}{2}=\frac{5}{10}$, $\frac{2}{5}=\frac{4}{10}$
Subtract: $\frac{5}{10}-\frac{4}{10}=\frac{1}{10}$

Step1: Identify fractions

Callie's fraction: $\frac{4}{5}$, Jon's fraction: $\frac{1}{2}$

Step2: Subtract fractions

Find common denominator (10): $\frac{4}{5}=\frac{8}{10}$, $\frac{1}{2}=\frac{5}{10}$
Subtract: $\frac{8}{10}-\frac{5}{10}=\frac{3}{10}$

Answer:

$\frac{1}{10}$
