Step-by-step solution

5 steps
  1. Decimal Conversion (and back to fraction)

    Convert each fraction to its decimal equivalent, add them, and then convert the sum back to a fraction.

    12=0.5\frac{1}{2} = 0.5 13=0.333...\frac{1}{3} = 0.333...

    Add the decimals:

    0.5+0.333...=0.8333...0.5 + 0.333... = 0.8333...

    To convert 0.8333... back to a fraction:
    Let x=0.8333...x = 0.8333...
    Multiply by 10: 10x=8.3333...10x = 8.3333... (Equation 1)
    Multiply by 100: 100x=83.3333...100x = 83.3333... (Equation 2)
    Subtract Equation 1 from Equation 2:

    100x−10x=83.3333...−8.3333...100x - 10x = 83.3333... - 8.3333... 90x=7590x = 75 x=7590x = \frac{75}{90}

    Simplify the fraction by dividing both numerator and denominator by their greatest common divisor, which is 15:

    x=75÷1590÷15=56x = \frac{75 \div 15}{90 \div 15} = \frac{5}{6}

    The simplified answer is 56\boxed{\frac{5}{6}}.

  2. Factoring out the Common Unit Fraction

    First, find the least common multiple (LCM) of the denominators, which is 6. This means the common unit fraction is 16\frac{1}{6}.
    Express each fraction as a multiple of this common unit fraction:

    12=36=3×16\frac{1}{2} = \frac{3}{6} = 3 \times \frac{1}{6} 13=26=2×16\frac{1}{3} = \frac{2}{6} = 2 \times \frac{1}{6}

    Now, add these expressions by factoring out the common unit fraction 16\frac{1}{6}:

    3×16+2×16=(3+2)×16=5×16=563 \times \frac{1}{6} + 2 \times \frac{1}{6} = (3+2) \times \frac{1}{6} = 5 \times \frac{1}{6} = \frac{5}{6}

    The simplified answer is 56\boxed{\frac{5}{6}}.

  3. Cross-Multiplication Method (Explicit Steps)

    This method involves multiplying the numerator of each fraction by the denominator of the other fraction, adding these products, and placing the sum over the product of the denominators.
    For 12+13\frac{1}{2} + \frac{1}{3}:
    Multiply the numerator of the first fraction (1) by the denominator of the second fraction (3): 1×3=31 \times 3 = 3.
    Multiply the numerator of the second fraction (1) by the denominator of the first fraction (2): 1×2=21 \times 2 = 2.
    Multiply the denominators together: 2×3=62 \times 3 = 6.
    Add the cross-products and place over the product of denominators:

    (1×3)+(1×2)2×3=3+26=56\frac{(1 \times 3) + (1 \times 2)}{2 \times 3} = \frac{3 + 2}{6} = \frac{5}{6}

    The simplified answer is 56\boxed{\frac{5}{6}}.

  4. Area Model (Grid Method)

    Imagine a rectangle divided into a grid where one dimension represents the first denominator and the other represents the second. For denominators 2 and 3, create a 2×32 \times 3 grid, resulting in 6 small squares.
    To represent 12\frac{1}{2}, shade one row (or column) out of the two. If we shade one row of three squares, we shade 3 out of 6 squares.
    To represent 13\frac{1}{3}, shade one column (or row) out of the three. If we shade one column of two squares, we shade 2 out of 6 squares.
    When combining these shaded areas, we have 3 squares from 12\frac{1}{2} and 2 squares from 13\frac{1}{3}. In total, we have 3+2=53+2=5 shaded squares out of the 6 total squares in the grid.
    Thus, the sum is 56\frac{5}{6}.
    The simplified answer is 56\boxed{\frac{5}{6}}.
