    Answer: 8 7/9 + 4 1/8 = 929
    /72  = 12 65/72  ≅ 12.9027778

    Step-by-step explanation:

    Conversion a mixed number 8 7

    9

    to a improper fraction: 8 7/9 = 8 7

    9

    = 8 · 9 + 7

    9

    = 72 + 7

    9

    = 79

    9

    To find new numerator:

    a) Multiply the whole number 8 by the denominator 9. Whole number 8 equally 8 * 9

    9

    = 72

    9

    b) Add the answer from previous step 72 to the numerator 7. New numerator is 72 + 7 = 79

    c) Write previous answer (new numerator 79) over the denominator 9.

    Eight and seven ninths is seventy-nine ninths

    Conversion a mixed number 4 1

    8

    to a improper fraction: 4 1/8 = 4 1

    8

    = 4 · 8 + 1

    8

    = 32 + 1

    8

    = 33

    8

    To find new numerator:

    a) Multiply the whole number 4 by the denominator 8. Whole number 4 equally 4 * 8

    8

    = 32

    8

    b) Add the answer from previous step 32 to the numerator 1. New numerator is 32 + 1 = 33

    c) Write previous answer (new numerator 33) over the denominator 8.

    Four and one eighth is thirty-three eighths

    Add: 79

    9

    + (33

    8

    ) = 79

    9

    + 33

    8

    = 79 · 8

    9 · 8

    + 33 · 9

    8 · 9

    = 632

    72

    + 297

    72

    = 632 + 297

    72

    = 929

    72

    For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators – LCM(9, 8) = 72. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 9 × 8 = 72. In the next intermediate step the fraction result cannot be further simplified by cancelling.

    In words – seventy-nine ninths plus thirty-three eighths = nine hundred twenty-nine seventy-seconds.
