divide the numerator by the denominator
First you would want to change the mixed number to an improper fraction. Then you can subtract
You convert the mixed numeral into an improper fraction. Now subtract the improper fraction from the whole number by putting the whole number over 1.
If its not an improper fraction then you cant....
You change them into improper or topheavy fractions.
An improper fraction is a fraction. It can't become a proper fraction.
You change it into an improper fraction, then simplify it, then if you want to, change it back to a mixed number.
You do the numerator divided by the denominator, then simplify the fractions if you can. (this is how you change a improper fraction to a mixed number, you cannot change a proper fraction to a mixed number)
I wouldconvert both to improper fraction,find a common multiple (CM),calculate equivalent fraction with CM as the denominator,add the numerators,change the improper fraction to a mixed fraction, if required,simplify the fractional part of the mixed fraction - if appropriate and required.
I don't think you can but, you can change an improper fraction to a decimal.
