Solve the following exercise:
To solve the fraction addition problem , follow these steps:
Step 1: Identify the least common denominator (LCD) of the fractions. The denominators are 4 and 6. The factors of 4 are 2 and 2, and the factors of 6 are 2 and 3. The LCD is the smallest number that both denominators divide into, which is 12.
Step 2: Convert each fraction to an equivalent fraction with the denominator of 12.
Step 3: For :
Find the equivalent fraction: Multiply both the numerator and denominator by 3 (since 4 * 3 = 12).
The equivalent fraction is .
Step 4: For :
Find the equivalent fraction: Multiply both the numerator and denominator by 2 (since 6 * 2 = 12).
The equivalent fraction is .
Step 5: Add the new fractions: .
Therefore, the sum of the fractions is .
Complete the following exercise:
\( \frac{3}{4}:\frac{5}{6}=\text{?} \)
Because fractions represent parts of different wholes! means 2 parts out of 4, while means 2 parts out of 6. You need a common denominator to add them properly.
List the multiples of each number until you find the smallest one they share:
The LCD is 12!
Always check if you can simplify! can be simplified to by dividing both numerator and denominator by their greatest common factor of 2.
Yes! Both fractions must have the same denominator before you can add them. Even if one fraction already has the LCD as its denominator, you still need to convert the other one.
You'll get the wrong answer! If you use 24 instead of 12, you'll get , which equals - the same as , but using the least common denominator makes calculations easier.
