Solve: Adding 3/5 and 6/10 - Fraction Addition Practice

To solve this problem, we need to add the fractions $\frac{3}{5}$ and $\frac{6}{10}$. Since $\frac{6}{10}$ is already expressed with the denominator of 10, we will convert $\frac{3}{5}$ to have the same denominator.

Step 1: Convert $\frac{3}{5}$ into a fraction with a denominator of 10. To do this, multiply both the numerator and the denominator by 2:

$\frac{3}{5} = \frac{3 \times 2}{5 \times 2} = \frac{6}{10}$

Step 2: Add the fractions $\frac{6}{10}$ and $\frac{6}{10}$:

$\frac{6}{10} + \frac{6}{10} = \frac{6 + 6}{10} = \frac{12}{10}$

Step 3: Simplify $\frac{12}{10}$. Both numerator and denominator can be divided by 2:

$\frac{12}{10} = \frac{12 \div 2}{10 \div 2} = \frac{6}{5}$

Thus, the sum $\frac{3}{5} + \frac{6}{10}$ simplifies to $\frac{6}{5}$.

Therefore, the correct answer is $\frac{6}{5}$ which corresponds to choice 3.
