The way you put 250 to 1000 as a fraction in simplest form is by dividing both the top numbers by a same number until you cannot divide with anything. For instanece in this cause the easiest way is by dividing by 250 because it is the biggest number you can divide both of the numbers which is 1/4. But if there are other problems you could divide by twos, fives or whichever number is eassiest for you.
