Video Solution

Solution Steps

00:00 Solution
00:03 We want to find the least common denominator
00:06 Therefore we'll multiply by 6, by 2 respectively for the common denominator 12
00:09 Remember to multiply both numerator and denominator
00:22 Let's calculate the multiplications
00:29 Add under common denominator
00:37 Calculate the numerator
00:40 And this is the solution to the question

Step-by-Step Solution

To solve the given problem, let's follow these steps:

  • Step 1: Find the Least Common Denominator (LCD)
    The denominators are 2, 6, and 12. The least common multiple (LCM) of these numbers is 12.
  • Step 2: Convert each fraction to have the common denominator of 12
    Here is how to convert each fraction:
    • 12\frac{1}{2} becomes 1×62×6=612\frac{1 \times 6}{2 \times 6} = \frac{6}{12}
    • 16\frac{1}{6} becomes 1×26×2=212\frac{1 \times 2}{6 \times 2} = \frac{2}{12}
    • 312\frac{3}{12} is already with denominator 12, so it remains 312\frac{3}{12}.
  • Step 3: Add the fractions
    Now add the equivalent fractions: 612+212+312=6+2+312=1112\frac{6}{12} + \frac{2}{12} + \frac{3}{12} = \frac{6 + 2 + 3}{12} = \frac{11}{12}.

Therefore, the solution to the problem is 1112\frac{11}{12}.

Answer

1112 \frac{11}{12}
