## anonymous one year ago I need help, so that's why Im gonaa ask this question: You have two numbers, with a difference of 2. If you divide them however, you get 2.2(with a bar on top of the second 2). What are the two answers. Please give me like an equation, and then the answer, thank you soooo much whoever answers this. (No thank you to the people who saw this and turned their head :) )

wah, no one's helping.. : (

let's call the numbers a and b so a-b=? and a/b=?

3. anonymous

a-b = 2 a/b= 2.22222222(repeating) or to make it more simple, a/b= 2 and two-ninths

4. freckles

right so we have: $a-b=2 \\ \frac{a}{b}=\frac{20}{9}$ You can solve the first equation for a by saying a=2+b now replace the a in the second equation with 2+b

5. freckles

$\frac{2+b}{b}=\frac{20}{9}$ solve for b

hhmmm I must be stupid

7. freckles

why?

8. anonymous

erm... lemme try that....|dw:1444595953765:dw| can't u say that the b/b is equal to 1 and say that 1+ wait no.....

9. freckles

you could multiply b and 9 on both sides some people like to call this technique cross-multiplication

10. freckles

9(2+b)=20b

11. anonymous

!! so simple!! see, im just dummy *crying can be heard*

12. anonymous

18 +9b = 20b 18 = 11b

13. anonymous

b= 11/18

14. freckles

18/11 not 11/18

15. anonymous

wait, but then if b=1 oh... so thats where I made my mistake

16. freckles

and we remember we had a=2+b so a=2+18/11
