Solve 2/4 + 1/4: Step-by-Step Fraction Addition with Visual Blocks

Q: Why don't I add the denominators together?

The denominator tells you what size pieces you're working with. Since both fractions have pieces of size $ \frac{1}{4} $, you keep working with fourths - just count how many you have total!

Q: How does the visual block diagram help?

The diagram shows the whole divided into 4 equal parts. You can see that 2 parts plus 1 part equals 3 parts out of the same 4 total parts.

Q: Do I need to simplify my answer?

Always check if you can simplify! In this case, $ \frac{3}{4} $ is already in lowest terms because 3 and 4 share no common factors except 1.

Q: What if the fractions had different denominators?

Then you'd need to find a common denominator first! But when denominators are the same (like both are 4), you can add directly.

Q: How can I double-check my work?

Think about it practically: $ \frac{2}{4} $ is half a whole, $ \frac{1}{4} $ is a quarter. Half plus a quarter equals three-quarters of the whole!

00:06 Let's solve this problem together.

00:09 First, we'll shade in the squares based on the numbers we're given. Watch carefully as I do this.

00:16 Next, let's count all the shaded squares and write this number as the top part, or numerator, of our new fraction.

00:23 For the bottom part, or denominator, we'll count the total number of squares we divided our shape into.

00:30 And there we have it! We've found our answer by creating a fraction from the shaded and total squares.

Follow each step carefully to understand the complete solution

Understand the problem

$\frac{2}{4}+\frac{1}{4}=$

Step-by-step solution

To solve this problem, let's follow these steps:

Step 1: Identify that both fractions $\frac{2}{4}$ and $\frac{1}{4}$ have the same denominator.
Step 2: Add the numerators together while keeping the denominator the same.
Step 3: Simplify the resulting fraction if possible.

Now, let's perform these steps:

Step 1: The denominator for both fractions is 4, so we can proceed with addition.

Step 2: Add the numerators: $2 + 1 = 3$ .

Step 3: Place the result over the common denominator: $\frac{3}{4}$ .

Therefore, the result of adding $\frac{2}{4} + \frac{1}{4}$ is $\frac{3}{4}$ .

This matches the correct choice, which is $\frac{3}{4}$ .

Final Answer

$\frac{3}{4}$

Key Points to Remember

Essential concepts to master this topic

Rule: Add numerators when denominators are the same
Technique: Keep denominator 4, add numerators: 2 + 1 = 3
Check: Verify $\frac{3}{4}$ represents 3 out of 4 equal parts ✓

Common Mistakes

Avoid these frequent errors

Adding both numerators and denominators
Don't add $\frac{2}{4} + \frac{1}{4} = \frac{3}{8}$ ! Adding denominators creates smaller pieces, not the correct sum. Always keep the same denominator and only add numerators.
