You multiply the outer (whole) number by the denominator and then add the numerator. You then place that answer over the original denominator.
For example, 2 3/4 you multiply the 2 by 4 and add 3. The answer would be 11/3.

To convert a mixed number to an improper fraction, you multiply the whole number by the denominator and add the numerator. This sum becomes the new numerator, while the denominator remains unchanged. For example, to convert the mixed number 3 1/2 to an improper fraction, multiply 3 by 2 and add 1, resulting in a numerator of 7. The denominator stays as 2, so the improper fraction is 7/2.
You can't. Improper and proper fractions are two different things. You can convert an improper fraction to a mixed number.
You take the bottom number and divided by the top number.
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.
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.
To convert an improper fraction to a mixed number, divide the denominator into the numerator. The answer is the whole number. Put any remainder over the original denominator to create the fraction part.
