A)To write 25/125 in its simplest form means to reduce it to its lowest term
hence
[tex]\frac{25}{125}=\frac{1}{5}[/tex][tex]B)\frac{15}{72\text{ }}\text{ in its lowest term = }\frac{5}{24}[/tex][tex]C)\text{ }\frac{20}{25\text{ }}\text{ in its lowest term =}\frac{4}{5}[/tex]D) 25/30 in its lowest term = 5/6
E) answer= 4/14 and 1/14
