Well, to keep it REALLY simple, 2 is a common factor for both. So how many times does to go into 38? How many times into 50??

38 / 2 = ?

OpenStudy (anonymous):

16

OpenStudy (anonymous):

Please use a calculator.

OpenStudy (anonymous):

19

OpenStudy (anonymous):

50 / 2 = ?

OpenStudy (anonymous):

25

So your new fraction is 19/25. Since 19 is a prime number, this fraction cannot be reduced further.
