steps:

1. multiply the whole number to the denominator
2. then add the numerator to the product. the result is the new numerator of the improper fraction
3. copy the original denominator

in the case above, (12 x 2) + 1 = 25
denominator is 2

so answer is = 25 / 2

well, if the question is mixed number, the given is already a mixed number. the steps i gave u is for converting a mixed to an improper fraction

25 / 2 is an improper fraction.

12½ , I would have thought , is a mixed number.

25/2 is an improper fraction, I do believe 12 and 1/2 is the mixed number.

12 1/2 is already a mixed number. Do you want to change it into improper fraction?

12 1/2
= (2 x 12 + 1)/2
= (24 + 1)/2
= 25/2
