00:03 We want to find the least common denominator

00:06 So we'll multiply by 2 for the common denominator 10

00:09 Remember to multiply both numerator and denominator

00:15 Let's calculate the multiplications

00:21 Let's add under common denominator

00:27 Let's calculate the numerator

00:30 And this is the solution to the question

Step-by-Step Solution

To solve this problem, let's break it down into clear, manageable steps:

Step 1: Identify the common denominator. Here, the denominators are 5 and 10. The least common denominator (LCD) is 10.
Step 2: Convert $\frac{1}{5}$ to an equivalent fraction with a denominator of 10. This means multiplying both the numerator and denominator by 2. Thus, $\frac{1}{5} = \frac{2}{10}$ .
Step 3: We already have $\frac{3}{10}$ with a denominator of 10, so no conversion is necessary.
Step 4: Add the two fractions: $\frac{2}{10} + \frac{3}{10} = \frac{2 + 3}{10} = \frac{5}{10}$ .
Step 5: Verify if the fraction can be simplified. Here, $\frac{5}{10}$ is already in its simplest form equivalent to $\frac{1}{2}$ , but, as part of the answer choices, it appears as $\frac{5}{10}$ .

Therefore, the correct answer is $\frac{5}{10}$ .
