Respuesta :

find the greatest common factor and then divide each number by it. 

in this case the gcf for 75 and 100 is 25.

75 divided by 25 = 3
100 divided by 25 = 4

so 75/100 simplified = 3/4
To reduce 75/100 you must find the Greatest Common Factor of 75 and 100 which would be 25, then you would divide each number by 25 to get 3/4.
