Solve the following exercise:
We will add the fractions , , and by first finding the common denominator.
The least common denominator (LCD) of the denominators 6, 3, and 12 is 12.
Let's convert each fraction to have this common denominator:
Now add the fractions:
.
The fraction can be simplified, but since the problem specifies to provide the answer in this form, we leave it as is.
Therefore, the solution to the problem is .
\( \frac{2}{4}+\frac{1}{4}= \)\( \)
Because fractions represent parts of different wholes! Adding directly would be like adding 1 slice of a 6-piece pizza to 1 slice of a 3-piece pizza - you need the same size pieces first.
List multiples of the largest number (12): 12, 24, 36... Check if smaller numbers divide evenly: 6 goes into 12 (yes!), 3 goes into 12 (yes!). So LCD = 12.
Not always! In this problem, the answer choices are given as twelfths, so is the expected format. Always match the format requested in the problem.
Lucky you! Like in this problem - it stays exactly the same. Only convert the fractions that need converting.
Yes, but it makes more work! You could use 24 instead of 12, but you'd get instead of . The LCD gives the simplest calculation.
