For a mixed fraction, you need an improper fraction, that is, a fraction whose numerator is larger than its denominator. So suppose the fraction is x/y where x > y.
Then divide x by y: that is x/y = q with a remainder r.
Then the mixed fraction for x/y is q r/y.
[Actually you need a numerator whose absolute value is greater than the positive denominator, but the fact that you ask this question suggests that you are nowhere near ready to go there.]
10 is an integer and there is no sensible way to express it as a fraction or mixed fraction.
600% is 6, which is an integer and there is no sensible way to express it as a mixed fraction.
Convert the mixed number to an improper fraction. Any fraction can be expressed as a decimal by dividing the denominator into the numerator.
Express the mixed fraction as an improper fraction and then proceed as you would with ordinary fractions. If the answer is an improper fraction, then remember to convert to a mixed fraction.
139/10 can be the improper fraction13 and 9/10 can be the mixed number1.39 as a fraction is 139/100.

Since 0.475 is less than 1, there is no need to express it as a mixed fraction. Expressed as a proper fraction in its simplest form, it is equal to 19/40 or nineteen fortieths.
If you express is as a mixed number, it is 8 and 4/100. However, if you express it as an improper fraction (as most people do), it is 804/100.
Since 3/4 is not a top heavy fraction, there is no need to express it as a mixed number.
6 3⁄8 = 51⁄8
150 is an integer: it is neither a fraction nor a mixed number. It can be expressed in the form of a rational fraction as 150/1 which is the simplest form. However, there is no sensible way to express it as a mixed number.
Since the fraction 5/6 is less than 1, there is no need to express it as a mixed number.
