## juciystar234 Group Title Please help me with these fractions!! (Below) one year ago one year ago

1. juciystar234 Group Title

$-\frac{ 1 }{ 7 } = X + 1\frac{ 2 }{ 3 }$

2. juciystar234 Group Title

$3\frac{ 1 }{ 4 } = 2 \frac{ 1 }{ 3 } + R$

3. mark_o. Group Title

before you do multiplication,can you changed mixed number to fraction? like 1 1/3 =? 3 1/4 =? , 2 1/3 =?

4. juciystar234 Group Title

|dw:1352337557785:dw|

5. juciystar234 Group Title

Yes

6. juciystar234 Group Title

11/ 3 = 3 2/3

7. juciystar234 Group Title

3 1/4 = 13/4

8. juciystar234 Group Title

2 1/3 = 7/3

9. mark_o. Group Title

ok good.. :D if its a mixed number changed the whole number to fraction with the same denominator so no prob on these .. 1 1/3 =is this like 1*3/3 +1/3 = 3/3 + 1/3 = 4/3 yes? 3 1/4 = 3*4/4 + 1/4 = 12/4 + 1/4 = 13/4 yes ? , 2 1/3 = 2*3/3 + 1/3 = 6/3 + 1/3 = 7/3 yes ? if yes now you can do the prob

10. mark_o. Group Title

yessssss ok

11. juciystar234 Group Title

okk go on

12. juciystar234 Group Title

sorry took me so long to answer i was getting milk and oreos :)

13. mark_o. Group Title

-1/7=x + 1 2/3 since the denominator are 7, t and 3 the common denominator is 7x3=21 $\frac{ -1 }{ 7 }*\frac{ 3 }{ 3 } - \frac{ 5 }{ 3 }*\frac{ 7 }{ 7 }$ $=\frac{ -3 }{ 21 }- \frac{ 35 }{ 21 }=\frac{ -38 }{ 21 } yes or no?$

14. juciystar234 Group Title

Ok hold on let me work it out....

15. juciystar234 Group Title

Yeah ok go on

16. mark_o. Group Title

ok take your time doing it but surely.. :D

17. juciystar234 Group Title

Me and my parents are working out y - 8 = 35 y - 8 + ? = 35 + ?

18. juciystar234 Group Title

Ok wait what???

19. juciystar234 Group Title

Work out what?

20. juciystar234 Group Title

y - 8 = 35 y - 8 + ? = 35 + ? This?

21. mark_o. Group Title

$3\frac{ 1 }{ 4 }= 2\frac{ 1 }{ 3 }+R$ $3\frac{ 1 }{ 4 }-2\frac{ 1 }{ 3 }=R$ the common denominator is 4x3 =12, therefore $=3*\frac{ 4 }{ 4 }+\frac{ 1 }{ 4 }-2*\frac{ 3 }{ 3 }+\frac{ 1 }{ 3 }$

22. mark_o. Group Title

can you try doing the next step?

23. juciystar234 Group Title

Um hold on let me try to do the problems my self and I will get back to you :)

24. mark_o. Group Title

ok meanwhile let me encode this for you

25. juciystar234 Group Title

We got y - 8 = 35 y - 8 + ? = 35 + ? I will try to get the rest

26. mark_o. Group Title

are you gonna be comfortable if we do them like these? 3 1/4 = 2 1/3 +R 13/4 = 7/3 +R common denominator is 4x3=12 13/4 - 7/3 =R 13/4 *3/3 - 7/3 *4/4 =R 39/12 - 28/12 =R 11/12=R yes?

27. juciystar234 Group Title

Ok I got -1/7=x + 1 2/3

28. juciystar234 Group Title

Hold on me and my parents are getting them we only need 3 1/4 = 2 1/3 + R

29. mark_o. Group Title

on the first on since you know how to convert mixed no. already -1/7=x+1 2/3

30. juciystar234 Group Title

5/3 = 1 2/3 yeah we did that then you have / and 3/ 21 and add them and get -38/21

31. mark_o. Group Title

-1/7=x+1 2/3 -1/7=x+ 5/3 -1/7- 5/3=x, LCD=21 (-1/7)(3/3)- (5/3)(7/7)=x, -3/21 - 35/21 =x x= -38/21 yes?

32. juciystar234 Group Title

Ok hold on be right back

33. mark_o. Group Title

ok very good.... :D

34. mark_o. Group Title

y - 8 = 35 y - 8 + ? = 35 + ? add 8 on both sides y - 8 + 8 = 35 + 8 y+0= 35+8 y= ?
