## mathhard Group Title 1/4+2/5=??? one year ago one year ago

1. mathhard

NEED HELP NOW!

2. geerky42

3. mathhard

IT WAS THE WRONG PROBLEM

4. Hero

Multiply the first fraction by 5/5 Multiply the second fraction by 4/4 Finally add both together

5. Ahsher97

turn them into decimals then back into a fraction, thats probably the easiest way for me

6. mathhard

TO HARD

7. AIK

5/20 +8/20?

8. AIK

you get the denominator on the same number for any addition or subtraction of different fractions

9. Hero

10. mathhard

THX AIK :3 XD

11. mathhard

NO

12. AIK

Do you want me to explain it to you how to get the do it or do you understand from what I gave you?

13. mathhard

I only do that since im in 4th grade

14. mathhard

AIK its fine the answer is easy now

15. mathhard

Wait no its not

16. AIK

you add both to get 13/20

17. mathhard

but the question is 2/5+1/4

18. Hero

@mathhard, you ever heard of equivalent fractions? If someone says to you that $\frac{2}{5} = \frac{4}{10}$ What goes through your mind?

19. mathhard

I only do that since im in 4th grade

20. Hero

Saying you're in 4th grade is not an excuse for not knowing.

21. mathhard

i cant do that jerk

22. abb0t

Don't you need to be 13 to use OS?

23. ArTFis

Common denominatorfor them would be 20. Mulitply 1/4 by 5 and 2/5 by 4. Then add and simplify.

24. mathhard

oh yeah one more thing its not an excuse

25. tyteen4a03

@abb0t OS might have a COPPA form somewhere, but otherwise yes, you need to be 13+ to use this site.

26. abb0t

LOL!

27. mathhard

Don't you need to be 13 to use OS? no @abb0t

28. tyteen4a03

@mathhard According to the OpenStudy Terms of Services, you must be 13+ and currently enrolled in a High School/University, OR you must be 18+. The full statement is outlined in the ToS here, under the Eligibility section: http://openstudy.com/terms-and-conditions You are currently violating the OpenStudy Terms of Use, and since that your attitude has not been great towards users, they have the option to report your account for ToS violation. Just saying ;)

29. mathhard

Im 18 i was kidding cant you take a joke

30. geerky42

Frankly, this is stupid, you can't tell how old users are behind computer. How can you tell if they are younger than 13?

31. karatechopper

BE NICE. And don't lie.

32. mathhard

shut up abb0t

33. karatechopper

Wow, an 18 year old not being able to do a fraction problem....never heard of that one before.

34. karatechopper

Oye. I said be nice please.

35. abb0t

36. mathhard

what is that @abb0t

37. Hero

So all this time, it was an 18 year old saying "too hard"?

38. mathhard

karatechopper im not a very smart person and you said to be nice|dw:1359073264680:dw|

39. mathhard

yes @Hero

40. karatechopper

I think an 18 year old, would be a bit more mature.

41. geerky42

@karatechopper "Wow, an 18 year old not being able to do a fraction problem...." It reminds me of this movie called "Stand and Deliver." Pretty good movie, I suggest you to watch it.

42. mathhard

@karatechopper still im not the brightest on earth

43. karatechopper

But still, what do you understand in this whole fraction problem. Have you even attempted it?

44. mathhard

yes i have.i need pictures to understand

46. karatechopper

47. mathhard
