Question

1. $3\frac{4}{5}+1\frac{2}{5}$

Explanation:

Step1: Split mixed numbers

$3\frac{4}{5} = 3 + \frac{4}{5}$, $1\frac{2}{5} = 1 + \frac{2}{5}$

Step2: Add whole numbers

$3 + 1 = 4$

Step3: Add fractions

$\frac{4}{5} + \frac{2}{5} = \frac{6}{5}$

Step4: Combine results

$4 + \frac{6}{5} = 4 + 1\frac{1}{5} = 5\frac{1}{5}$

Answer:

$5\frac{1}{5}$ (or $\frac{26}{5}$)
