We are given the following fractions:


(25)/(30)-(21)/(30)

To subtract fractions with the same denominator, in this case, 30, we leave the same denominator and operate the numerators, like this:


(25)/(30)-(21)/(30)=(25-21)/(30)=(4)/(30)

Now we simplify the fraction by dividing both parts by 2:


(4)/(30)=((4)/(2))/((30)/(2))=(2)/(15)
