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.
multiply the denominator by the whole number then add the numerator and you have an improper fraction
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.
A mixed number can be converted to an improper fraction.
It is best to convert the mixed fraction to an improper fraction. They are then added together in the same way as proper fractions are added together.
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.
The mixed number consists of a whole number and a fraction. Multiply the denominator of the fraction portion by the whole number and to this product add the numerator of the fraction portion. This value is the numerator of the new improper fraction. The denominator of the new improper fraction is the same as the denominator of the original fraction portion of the mixed number.
To convert a mixed number to an improper fraction, multiply whole number part by the denominator of the fraction part, then add the numerator to the product. The result is the numerator of the improper fraction. The denominator remains the same. For example, to convert 2 3/8 to an improper fraction, multiply 2*8 = 16, then add 3 to get 19. The improper fraction is 19/8.
Make it into an both numbers an improper fraction and then do the opperation.
By changing the mixed number into an improper fraction and ensuring that they both have the same denominators simply then subtract one improper fraction from the other improper fraction.
If you are using the same number, then the improper fraction and mixed number are equal.
