9. how you would convert the repeating, non terminating decimal to a fraction? explain the process as you solve the problem. 0.1515
I don't understand this question can someone help explain this?
let x = .151515...
times 100
100x = 15.151515...
subtract them:
notice the decimals line up and will subtract to get zeros
99x = 15
x = 15/99 = 5/33
check with your calculator by dividing 5 by 33
Reiny is correct but in the part where he says "subtract them" he means subtract 100 by 0.151515 which will equal 99. so thats where he got 99 from. then 99 x 0.151515 will equal 15. Try dividing 15 by 99... did you get 0.151515...? so 15/99 in fraction form is also 5/33. to check if 0.151515 = 5/33 divide 5 by 33. anyway your final answer is 5/33
hope this cleared it up a bit, if not read it again carefully until you get it. :)

@Star Lord, you are a life saver. I praise you. Iβm horrible at math XD
Hey Star Lord and Reiny, I'm still kind of confused about the parts with the 100, can you help me understand?
I'm not here from Connexus. I go to a public propel school. We just use almost the same curriculum. I came here because I don't understand this either and was hoping someone could explain this because I didn't understand my lesson.
For number 10 -
turn 0.57 into a fraction. So 0.57 into a fraction is obviously 57/100, now since its is a fraction it is rational.
