Solution Steps

00:00 Solution
00:03 We want to find the least common denominator
00:06 Therefore we'll multiply by 2 and 3 respectively for the common denominator 12
00:10 Remember to multiply both numerator and denominator
00:21 Let's calculate the multiplications
00:27 Add under common denominator
00:37 Calculate the numerator
00:41 And this is the solution to the question

Step-by-Step Solution

To solve this problem, we will follow these steps:

  • Step 1: Find the least common multiple (LCM) of the denominators.
  • Step 2: Convert each fraction to an equivalent fraction with the common denominator.
  • Step 3: Add the converted fractions.
  • Step 4: Simplify the resulting fraction if possible.

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 26 \frac{2}{6} to have the denominator 12: 26=412 \frac{2}{6} = \frac{4}{12} by multiplying numerator and denominator by 2.
- Convert 14 \frac{1}{4} to have the denominator 12: 14=312 \frac{1}{4} = \frac{3}{12} by multiplying numerator and denominator by 3.
- 212 \frac{2}{12} already has the denominator 12, so it remains unchanged: 212 \frac{2}{12} .

Step 3: Add the numerators of the converted fractions:
412+312+212=4+3+212=912 \frac{4}{12} + \frac{3}{12} + \frac{2}{12} = \frac{4 + 3 + 2}{12} = \frac{9}{12} .

Step 4: Simplify the fraction if possible. Here, 912 \frac{9}{12} can be simplified by dividing both numerator and denominator by their greatest common divisor, which is 3:
912=34 \frac{9}{12} = \frac{3}{4} .

Therefore, the solution to the problem is 912 \frac{9}{12} .

Answer

912 \frac{9}{12}
