## AonZ 2 years ago Help me pls!!! my coaching teacher is going 2 kill me

1. AonZ

$\frac{ 2 }{ 9 }$ of the people on a restaurant are adults. if there are 95 more children than adults, how many children are there in the restaurant

2. Kuoministers

he really gonna kill u???

3. AonZ

yes

4. Kuoministers

i would be dead scared ^^

5. AonZ

pls help

6. FirstFrostByte

Okay I'll try :)

7. Kuoministers

7/9 people are children

8. AonZ

i know but in number?

9. Kuoministers

how would i know.. @FirstFrostByte is pro

10. AonZ

uhhhhh frost bite?

11. FirstFrostByte

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

im pretty sure u lost him

13. FirstFrostByte

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

14. AonZ

well i kinda like that method u just did

15. FirstFrostByte

@AonZ You know what a variable is right?

16. AonZ

not really

17. FirstFrostByte

Okay let me do this step by step.

18. AonZ

ty

19. FirstFrostByte

$9/9$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

yes

21. AonZ

100%

22. FirstFrostByte

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

ohhhhh i get now

24. AonZ

i get the question

25. AonZ

it is just that part that i got lost

26. AonZ

yay so their is 133 children

27. FirstFrostByte

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.

29. AonZ

ty frost byte my coaching techer will not kill me now

30. AonZ

done my homework

31. FirstFrostByte

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

ohhhh i think this is a better method for me

33. FirstFrostByte

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.
