Solve the following exercise:
To solve this problem, we will follow these steps:
Step 1: The denominators are 6, 4, and 12. The least common multiple of these numbers is 12.
Step 2: Convert each fraction to have the common denominator of 12.
- Convert to have the denominator 12: by multiplying numerator and denominator by 2.
- Convert to have the denominator 12: by multiplying numerator and denominator by 3.
- already has the denominator 12, so it remains unchanged: .
Step 3: Add the numerators of the converted fractions:
.
Step 4: Simplify the fraction if possible. Here, can be simplified by dividing both numerator and denominator by their greatest common divisor, which is 3:
.
Therefore, the solution to the problem is .
\( \frac{2}{4}+\frac{1}{4}= \)\( \)
Fractions represent parts of a whole, and each denominator creates different-sized parts. You need same-sized parts (common denominator) to add them correctly!
List multiples of each: 6(6,12,18...), 4(4,8,12,16...), 12(12,24...). The smallest number that appears in all lists is 12.
It depends on what the problem asks for! If the answer choices show , give that. If they want simplest form, then reduce to .
Great! That fraction stays the same. In this problem, already had denominator 12, so we kept it as .
You could, but it's often harder and may create rounding errors. Stick with fractions - the common denominator method is more accurate and matches your answer choices!
