Video Solution

Step-by-Step Solution

We need to find a common denominator for the fractions 13\frac{1}{3} and 16\frac{1}{6} in order to add them together.

Step 1: Identify the least common denominator (LCD).

  • The denominators are 3 and 6.
  • The least common multiple (LCM) of 3 and 6 is 6. Hence, the LCD is 6.

Step 2: Convert each fraction to an equivalent fraction with the LCD of 6.

  • 13\frac{1}{3} needs to be converted. Multiply both numerator and denominator by 2: 13=1×23×2=26\frac{1}{3} = \frac{1 \times 2}{3 \times 2} = \frac{2}{6}.
  • 16\frac{1}{6} already has the denominator as 6, so it remains 16\frac{1}{6}.

Step 3: Add the fractions.

  • Now that the denominators are the same, we can add the numerators: 26+16=2+16=36\frac{2}{6} + \frac{1}{6} = \frac{2 + 1}{6} = \frac{3}{6}.

Step 4: Simplify the result.

  • 36\frac{3}{6} can be simplified by dividing both the numerator and the denominator by their greatest common divisor (GCD), which is 3: 36=3÷36÷3=12\frac{3}{6} = \frac{3 \div 3}{6 \div 3} = \frac{1}{2}.

Thus, the result of the addition of 13\frac{1}{3} and 16\frac{1}{6} is 12\frac{1}{2}.

Therefore, the solution to the problem is 12\frac{1}{2}.

Answer

    The fraction 34 \frac{3}{4} needs to be converted to an equivalent fraction with a denominator of 8. To do this, multiply both the numerator and the denominator by 2: 34=3×24×2=68 \frac{3}{4} = \frac{3 \times 2}{4 \times 2} = \frac{6}{8} .
    The fraction 38 \frac{3}{8} already has a denominator of 8, so it remains the same: 38 \frac{3}{8} .
  • Step 3: Add the Fractions
    With a common denominator, add the numerators while keeping the denominator the same: 68+38=6+38=98 \frac{6}{8} + \frac{3}{8} = \frac{6 + 3}{8} = \frac{9}{8} .
  • Step 4: Simplify the Fraction if Necessary
    The fraction 98 \frac{9}{8} is already in its simplest form, but it is an improper fraction. If desired, it can be expressed as a mixed number: 118 1 \frac{1}{8} . However, 98 \frac{9}{8} as a fraction suffices for this problem.

Therefore, the solution to the problem is 98 \frac{9}{8} .

Step-by-Step Solution

To solve this problem, we will add the fractions 412 \frac{4}{12} and 56 \frac{5}{6} . Follow these steps:

  • Step 1: Find the least common denominator (LCD) of the fractions. The denominators are 12 and 6. The LCD is 12 because it is the smallest number into which both 12 and 6 divide evenly.
  • Step 2: Convert the fractions to have the common denominator 12. The fraction 412 \frac{4}{12} is already expressed with this denominator.
  • Step 3: Convert 56 \frac{5}{6} to an equivalent fraction with a denominator of 12. To do this, determine what number times 6 gives 12, which is 2. Multiply both the numerator and the denominator of 56 \frac{5}{6} by 2:
  • 56=5×26×2=1012\frac{5}{6} = \frac{5 \times 2}{6 \times 2} = \frac{10}{12}
  • Step 4: Add the fractions now that they have the same denominator:
  • 412+1012=4+1012=1412\frac{4}{12} + \frac{10}{12} = \frac{4 + 10}{12} = \frac{14}{12}
  • Step 5: Simplify the resulting fraction, 1412 \frac{14}{12} . Both the numerator and the denominator are divisible by 2, so:
  • 1412=14÷212÷2=76\frac{14}{12} = \frac{14 \div 2}{12 \div 2} = \frac{7}{6}

Thus, the sum of the fractions 412 \frac{4}{12} and 56 \frac{5}{6} is 76 \frac{7}{6} .

Therefore, the correct answer is 76 \frac{7}{6} .
