Question

Please help on this one I am a bad student but good

Answer 1

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)`
