im not good with percents can anyone help? The total rainfall in Forks, Washington, this October was 8 3/8in. In September, 60% less rain fell than in October. How much rain fell in September in Forks, Washington? Express your answer as a mixed number in simplest form.

OpenStudy (misssmartiez):

Put 8 3/8ths in decimal form and then 60%. Then compare it. Then, turn it back into a mixed number. c:. 8. (3 divided by 8?) = 8.375. 8.375 less than 0.6 (60 x 100 = 0.6) Now what do we have to do to figure out how much we have gotten in September?

OpenStudy (misssmartiez):

8.375 _ 0.6 = R What operation do we need to do. Addition is out.

OpenStudy (twistrose):

um divide?

OpenStudy (misssmartiez):

"The total rainfall in Forks, Washington, this October was 8 3/8in. In September, 60% less rain fell than in October. " LESS. How do we get that LESS number.

OpenStudy (twistrose):

subtract

OpenStudy (misssmartiez):

Hmm, not sure if we are doing the proper procedure. However, I did multiplication, which has given me 5.025. In fraction form, 5 1/40.

OpenStudy (misssmartiez):

I checked too, everyone that has done this question had gotten 5 1/40, just did another way to figure it out.

OpenStudy (twistrose):

oh ok thanks

OpenStudy (misssmartiez):

No problem! Usually I do multiplication for these problems, conducting them into decimals before, than later converting it back!
