Video Solution

Solution Steps

00:00 Solve
00:03 We want to find the least common denominator
00:06 Therefore we'll multiply by 3, by 2 respectively for the common denominator 12
00:09 Remember to multiply both numerator and denominator
00:21 Let's calculate the multiplications
00:31 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 addition of these two fractions, we'll proceed as follows:

  • Step 1: Determine the least common denominator (LCD) of the fractions.
    The denominators are 4 and 6, and the smallest number that is a multiple of both is 12. Thus, the LCD is 12.
  • Step 2: Convert each fraction to an equivalent fraction with the denominator 12.
    - For 34 \frac{3}{4} , multiply both numerator and denominator by 3: 3×34×3=912 \frac{3 \times 3}{4 \times 3} = \frac{9}{12} .
    - For 16 \frac{1}{6} , multiply both numerator and denominator by 2: 1×26×2=212 \frac{1 \times 2}{6 \times 2} = \frac{2}{12} .
  • Step 3: Add the converted fractions.
    912+212=9+212=1112 \frac{9}{12} + \frac{2}{12} = \frac{9 + 2}{12} = \frac{11}{12} .

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

Answer

1112 \frac{11}{12}
