Video Solution

Solution Steps

00:06 Let's find the missing number.

00:09 Notice, the result shares the same denominator.

00:13 So, our missing number needs that same denominator.

00:17 Now, let's focus on the numerators.

00:20 We'll discover the missing number and add it to the numerator.

00:24 And that's how we solve this problem!

Step-by-Step Solution

To solve the problem $\frac{2}{5} - \_ = \frac{1}{5}$ , we will use the concept of subtraction of fractions to find the missing fraction.

Let's follow these steps:

Step 1: The initial fraction (minuend) is $\frac{2}{5}$ and the result (difference) is $\frac{1}{5}$ .

Step 2: Apply the formula from our analysis: $\text{Minuend} - \text{Difference} = \text{Subtrahend}$ . That means $\frac{2}{5} - \frac{1}{5} = \_$ .

Step 3: Perform the subtraction by subtracting the numerators:

$\frac{2}{5} - \frac{1}{5} = \frac{2 - 1}{5} = \frac{1}{5}$ .

Therefore, the missing fraction is $\frac{1}{5}$ .
