Video Solution

Solution Steps

00:05 Let's solve the problem together.
00:08 We need to find the least common denominator.
00:12 So, we'll multiply both by two, to get a common denominator of four.
00:17 Remember, multiply both the top and bottom parts!
00:21 Now, let's calculate these multiplications.
00:26 Add them together under the common denominator.
00:31 Then, find the sum of the top numbers.
00:35 And that's how we solve this problem!

Step-by-Step Solution

To solve the problem of adding the fractions 12 \frac{1}{2} and 24 \frac{2}{4} , we can follow these steps:

  • Step 1: Convert the fraction 12 \frac{1}{2} to have the same denominator as 24 \frac{2}{4} .
  • Step 2: Add the two fractions.
  • Step 3: Simplify the sum, if necessary.

Now, let's execute these steps in detail:
Step 1: Convert 12 \frac{1}{2} to a fraction with a denominator of 4. To do this, multiply both the numerator and the denominator by 2. Thus, 12=1×22×2=24 \frac{1}{2} = \frac{1 \times 2}{2 \times 2} = \frac{2}{4} .
Step 2: Now, add the fractions 24+24 \frac{2}{4} + \frac{2}{4} . Since the denominators are the same, we add the numerators and keep the common denominator: 2+24=44 \frac{2+2}{4} = \frac{4}{4} .
Step 3: Simplify 44 \frac{4}{4} , which equals 1. However, the problem asks for the sum in fraction form, so we present it as 44 \frac{4}{4} .

Therefore, the solution to the given problem is 44 \frac{4}{4} .

Answer

44 \frac{4}{4}
