To solve this problem, we'll follow these steps:
Now, let's work through each step:
Step 1: The denominators are 5, 3, and 15. The LCM of these numbers is 15.
Step 2: Convert each fraction:
Step 3: Add the numerators of the converted fractions:
Step 4: The fraction is already in simplest form.
Therefore, the solution to the problem is .
\( \)\( \frac{4}{5}+\frac{1}{5}= \)
The LCM is the smallest number that all denominators divide into evenly. Since 15 ÷ 5 = 3, 15 ÷ 3 = 5, and 15 ÷ 15 = 1, the number 15 works perfectly!
Sometimes you'll need to find larger LCMs. For example, with denominators 4, 6, and 9, the LCM would be 36. The process stays the same - just convert each fraction using the LCM.
Yes, if possible! However, is already in simplest form because 16 and 15 share no common factors other than 1.
You could, but you might get messy decimals that are hard to work with. The LCM method keeps everything as exact fractions, which is usually cleaner and more accurate.
Great! Like in this problem - it stays exactly the same. You only need to convert the other fractions to match this denominator.
Divide the LCM by the original denominator. For : 15 ÷ 5 = 3, so multiply both numerator and denominator by 3 to get .
