6. FirstFrostByte Group Title

Okay I'll try :)

7. Kuoministers Group Title

7/9 people are children

8. AonZ Group Title

i know but in number?

9. Kuoministers Group Title

how would i know.. @FirstFrostByte is pro

10. AonZ Group Title

uhhhhh frost bite?

11. FirstFrostByte Group Title

95 more children, so 7/9 of the people the children portion is 95. Knowing that: (7/9 - 2/9)*x = 95 5/9 * x = 95 So the total people would be: 95 * 9/5 = 171 Next we do: 2/9 *171 = 38 To get the adult count. And this for the children count: 7/9 *171 = 133

12. Kuoministers Group Title

im pretty sure u lost him

13. FirstFrostByte Group Title

There are multiple ways to solve this... I don't know which method he wants...

14. AonZ Group Title

well i kinda like that method u just did

15. FirstFrostByte Group Title

@AonZ You know what a variable is right?

16. AonZ Group Title

not really

17. FirstFrostByte Group Title

Okay let me do this step by step.

18. AonZ Group Title

ty

19. FirstFrostByte Group Title

$9/9$would be everyone in the restaurant. Given to us is 2/9 is adults. So that leaves? 9 - 2 = 7 7/9 Must be children. Do you understand so far before I continue?

20. AonZ Group Title

yes

21. AonZ Group Title

100%

22. FirstFrostByte Group Title

For each "9" people there are 5 more then adults. So: Let's use a variable now which will be "P" for people. 5/9 * P = 95 Now let's flip over 95 to the other side. 95 * 9/5 (it becomes 9/5 due to a rule) = P 95 * 9/5 = 171 Correct? Now we know the total amount of people. Do you understand?

23. AonZ Group Title

ohhhhh i get now

24. AonZ Group Title

i get the question

25. AonZ Group Title

it is just that part that i got lost

26. AonZ Group Title

yay so their is 133 children

27. FirstFrostByte Group Title

Okay. So: Since we now know the total: Next we do: 2/9(Adults) *171 = 38 Adults And this for the children count: 7/9(Children) *171 = 133 Children So there for 133 Children are in the restaurant.

ty frost byte my coaching techer will not kill me now

30. AonZ Group Title

done my homework

31. FirstFrostByte Group Title

Haha :) I'm happy you didn't die. There is another method you could do: Take 95 / 5(Since we know there is 5 more children then adults.) And you get 19. So you need 19 sets of 2 adults and 7 children to equal the total. 19 x 2 = 38 Adults 19 x 7 = 133 Children Check your work: 133 - 38 = 95 See?

32. AonZ Group Title

ohhhh i think this is a better method for me

33. FirstFrostByte Group Title

I guess. But if your in Pre-Algebra. Go with the first method. I'm cleaner and faster. And you'll use it more often too.
