Video Solution

Solution Steps

00:07 Let's find the unknown value in our problem.

00:12 First, reduce the fraction to its simplest form.

00:16 Remember to divide, both the top and bottom numbers.

00:21 Here's our reduced fraction. Now, let's substitute it back in.

00:38 The solution has the same bottom number, so the unknown shares it too.

00:43 Let's figure out the unknown by just looking at the top numbers.

00:47 And there you have it! That's the answer to our question.

Step-by-Step Solution

To find the missing number in the equation $? + \frac{2}{8} = \frac{3}{4}$ , we will follow these steps:

Step 1: Simplify the fraction $\frac{2}{8}$ to $\frac{1}{4}$ .
Step 2: Recognize that we need to find a fraction that, when added to $\frac{1}{4}$ , results in $\frac{3}{4}$ .
Step 3: Set up the equation $? + \frac{1}{4} = \frac{3}{4}$ .
Step 4: Solve for the missing fraction by subtracting $\frac{1}{4}$ from $\frac{3}{4}$ :
$? = \frac{3}{4} - \frac{1}{4} = \frac{2}{4}$ .
Step 5: Simplify the resulting fraction: $\frac{2}{4} = \frac{1}{2}$ .

Therefore, the missing number in the equation is $\frac{2}{4}$ .
