a. \( \frac{1}{4}+\frac{1}{2}= \)

To solve \( \frac{1}{4}+\frac{1}{2} \), first, you need a common denominator. The least common denominator of 4 and 2 is 4. So, you can rewrite \( \frac{1}{2} \) as \( \frac{2}{4} \). Now, the equation looks like this: \( \frac{1}{4} + \frac{2}{4} = \frac{3}{4} \). So, the answer is \( \frac{3}{4} \)! Next time you're adding fractions, remember to find that common denominator first—it's the golden rule! This way, you’ll avoid any complicated juggling of numbers and keep it straightforward. Just think of it as making sure everyone at the party has the same size drink before sharing!
