Ответ:
the same denominator.
For this little problem, don't worry about the signs yet. Just make both
fractions have the same denominator. I suggest you change the first one
to something over 250.
When your fractions have the same denominator, you get the sum or difference
like this:
-- The numerator of the answer is the sum or difference of the two numerators.
-- The denominator of the answer is the same as the denominator of the two fractions.
