Step-by-Step Solution

To solve the problem of adding 34 \frac{3}{4} and 38 \frac{3}{8} , let's follow a systematic approach:

  • Step 1: Identify the Common Denominator
    The denominators are 4 and 8. The least common multiple (LCM) of 4 and 8 is 8. Thus, 8 will be our common denominator.
  • Step 2: Convert Fractions to Common Denominator
    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} .

Answer

98 \frac{9}{8}
