Solve the following exercise:
To solve the problem of adding and , we need to first convert these fractions to have a common denominator.
Step 1: Find the least common denominator (LCD).
   - The denominators of the fractions are  and .
   - The common denominator can be found by multiplying  and , which gives us .
Step 2: Convert each fraction to an equivalent fraction with the common denominator of .
   - For , multiply both the numerator and the denominator by :
     .
   - For , multiply both the numerator and the denominator by :
     .
Step 3: Add the resulting fractions.
   - .
Therefore, the solution to the problem is , which simplifies our answer.
Complete the following exercise:
\( \frac{3}{4}:\frac{5}{6}=\text{?} \)
Because fractions represent parts of different wholes! Adding (parts of 8) to (parts of 3) is like adding apples to oranges. You need the same denominator to add properly.
Since 8 and 3 share no common factors (they're relatively prime), their LCD is simply . For other numbers, find the smallest number both denominators divide into evenly.
It's good practice to check if your answer can be simplified! can be simplified to by dividing both numerator and denominator by 2.
The process stays the same! Find the LCD, convert both fractions, then add. For large numbers, try finding the greatest common factor first to make the LCD smaller.
Yes, but it makes the problem harder! Any common multiple works, but using the LCD keeps your numbers smaller and easier to work with.
