Stephanie what don't you get be more specific so i can help? If you don't get the ratio lesson allow me to give you another way to solve it that i found easier. you can use the is over of % over a 100 for this. for example 2 is to 1000 as 5 and 1/2 is to what? place 2 over 1000 and change the fraction to a decimal 5.5 over xcross multiply 5.5 x 1000 and divide by 2 to get your answer 2750
