5. lgbasallote

7. lgbasallote

8. shannyd

12 pennies

9. shannyd

I Mean 10 .sorry

10. lgbasallote

11. shannyd

7

12. lgbasallote

right

13. lgbasallote

so now do this $\frac{\text{not canadian}}{\text{total number of pennies}} \times 100$ got it?

14. shannyd

7/12 * 100 ?

15. lgbasallote

17. shannyd

7/10 * 100 ?

18. lgbasallote

right

19. shannyd

I Got My Questions Mix sorry but it's 10

20. shannyd

So the answer would be 7/10 ?

21. lgbasallote

x 100

22. lgbasallote

divide 7/10 then multiply 100

23. shannyd

I Got 70

24. shannyd

& That's not a choice

25. lgbasallote

well then...don't multiply by 100

26. lgbasallote

multiplying by 100 gives you the percent... so if you just want a decimal answer, don'tmultiply

27. shannyd

all im getting is 70

28. lgbasallote

don't multiply by 100

29. shannyd

it's still not right

30. lgbasallote

why so? what did you get?

31. shannyd

0.7

32. lgbasallote

and that's not right?

33. shannyd

nope it's either .13/10 3/10 7/10 or 10/3

34. lgbasallote

well...it's obviously 7/10 then....since it's a part of the solution you did...
