2. anonymous

@satellite73 no actually i dont

3. anonymous

they cost like \$8 at the drug store

4. anonymous

you are on a computer maybe? have a cell phone?

5. AbdullahM

Make the mixed fractions into improper fractions.

6. AbdullahM

Do you know how to do that?

7. anonymous

Does this help?

8. anonymous

or do what @AbdullahM said $5\tfrac{1}{6}=\frac{6\times 5+1}{6}=\frac{31}{6}$

9. anonymous

okay so i didnt do anything in middle school and now i actually wanna pass but i dont have background knowledge so all this is very hard on me

10. anonymous

@SurpriseBreeze thank you

11. AbdullahM

@satellite73 made $$\sf\Large 5\frac{1}{6}$$ into an improper fraction. Can you do the same for $$\sf\Large 2\frac{2}{3}$$

12. AbdullahM

Nevermind, you got the answer and that's all what you were interested in. You didn't want to learn...

13. anonymous

@AbdullahM i do not no what a improper fraction is

14. anonymous

it is a fraction where the top is bigger that the bottom

15. anonymous

like $\frac{31}{6}$

16. anonymous

another way to say it is a fraction that is larger than 1

17. anonymous

@satellite73 then why do you turn 5 1/6 into a improper fraction if its already proper?

18. AbdullahM

Because you can not add or subtract fractions when they are mixed fractions.

19. AbdullahM

and when you want to add/subtract them you need to have the same denominator for both fractions.

20. anonymous

@AbdullahM mixed fraction?

21. AbdullahM

mixed fraction is: $$\sf\Large 5 \frac{1}{6}$$

22. anonymous

@AbdullahM oh

23. AbdullahM

You're in high school now?

24. anonymous

@AbdullahM by luck yes

25. AbdullahM

You're going to really review on your basics if you want to go take higher level math courses in college and stuff...

26. anonymous
