7.79 = 779/100
0.714285 does not convert to a mixed fraction, just a fraction. It is: 142857/200000
because a proper fraction is less than1 and a mixed fraction is greater than 1
You can either add the fractional parts and, if required, convert the answer to a mixed fraction and then add the integer part to the integer parts of the two original numbers; or change both numbers to top-heavy (or improper) fractions, add them and then convert the answer to a mixed fraction.
