Sixth grade raised 500 seventh grade raised 625 and eighth grade raised 1000 what fraction of money did the eighth grade raise?

Answer 1

To answer this question you need to first add all of the numbers together this will give you 2125, which is your denominator. To get the fraction raised by the 8th grade you simply put the number that they raised (1000) over your denominator (2125). To get the final answer you reduce the fraction to its lowest form, so you divide by the lowest number that will go into both the numerator and denominator, which in this case is 125. So :1000/125 = 8. & 2125/125 = 17. So your final answer should be 8/17. Hopefully this helps!
