4. $5\\frac{1}{5}-2\\frac{1}{2}$\na. $2\\frac{7}{10}$\nb. $2\\frac{1}{3}$\nc. $3\\frac{5}{10}$\nd. $3\\frac{1}{3}$
Answer
Explanation:
Step1: Convert to improper fractions
$5\frac{1}{5} = \frac{26}{5}$, $2\frac{1}{2} = \frac{5}{2}$
Step2: Find common denominator
$\frac{26}{5} = \frac{52}{10}$, $\frac{5}{2} = \frac{25}{10}$
Step3: Subtract the fractions
$\frac{52}{10} - \frac{25}{10} = \frac{27}{10}$
Step4: Convert to mixed number
$\frac{27}{10} = 2\frac{7}{10}$
Answer:
A. $2\frac{7}{10}$
