8 3/8 is the fraction for october

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

5. randomecorner

so 2/5 times8 and 3/8?

6. anonymous

yes

7. randomecorner

6/40

8. randomecorner

am i right?

9. anonymous

no

10. randomecorner

8 and 6/40

11. randomecorner

eight stays the samebecause its a whole numbah

12. randomecorner

so is that right?

13. anonymous

not with multiplication. 8 gets mulitiplied by 2/5 as well

14. randomecorner

so how do we dot hat/

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

18. randomecorner

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

19. anonymous

no reciprocal

20. randomecorner

but in the space its a mixed number fraction2

21. anonymous

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

22. randomecorner

both by 2?

23. anonymous

|dw:1433960372246:dw|

24. anonymous

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

25. randomecorner

but it needsto be a mixed fraction

26. randomecorner

so i needa whole number and a fraction

27. anonymous

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

28. randomecorner

its62 u mean

29. anonymous

no, 67

30. anonymous

wait, where did you mean 62?

31. randomecorner

uright lol i divided wrong

32. randomecorner

they cant because 67 is a prime numbah

33. 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.

34. anonymous

$\frac{ 67 }{ 20 }=3\frac{ 7 }{ 20 }$

35. randomecorner

oh ok so thats the answer?

36. anonymous

yes

37. randomecorner
