60% less means september's rain was 40% of october's. 40% as a fraction is 2/5. Multiply the October number by 2/5

write 8 3/8 as an improper fraction, then multiply

so 130/40 but we do reciprical so its40 over 134

- anonymous

no reciprocal

- randomecorner

but in the space its a mixed number fraction2

- anonymous

134/40 then reduce by dividing num & den by 2

- randomecorner

both by 2?

- anonymous

|dw:1433960372246:dw|

- anonymous

by 2 because that's the biggest number that goes into 134 and 40

- randomecorner

but it needsto be a mixed fraction

- randomecorner

so i needa whole number and a fraction

- anonymous

yes, so turn 67/20 into a mixed number. What's the closest number to 67 that 20 divides into?

- randomecorner

its62 u mean

- anonymous

no, 67

- anonymous

wait, where did you mean 62?

- randomecorner

uright lol i divided wrong

- randomecorner

they cant because 67 is a prime numbah

- anonymous

20 is the denominator.
20* 1 = 20
20*2 = 40
20*3 = 60
20*4 = 80
67 is between 60 and 80, so the whole number part is 3.
Basically if you divide 67 by 20 you would get 3 with a remainder of 7.

- anonymous

\[\frac{ 67 }{ 20 }=3\frac{ 7 }{ 20 }\]

- randomecorner
