Perform the indicated operation. 10 3/7 + 19 5/9
DanielleElmas [232]
Given expression is

10 \frac{3}{7} + 19 \frac{5}{9}

Now convert mixed fraction as improper fraction as

10 \frac{3}{7} + 19 \frac{5}{9} =  \frac{10*7 + 3}{7} +  \frac{19*9+5}{9}
                                                         =  \frac{73}{7}  +  \frac{176}{9}
                                                          =  \frac{73*9 + 176 * 7}{63}
                                                         =  \frac{657 + 1232}{63} =  \frac{1889}{63}
Now we can convert \frac{1889}{63 } = 29 \frac{62}{63}

So the answer is 29 \frac{62}63}
