## Lepgirl 3 years ago Distribution with fractions. -2(6 - 9/2 x)

1. atjari

Do you know how to remove brackets in this type of questions?

2. Lepgirl

no

3. atjari

Nw let's take a simple example. 2(3-2) Let's first remove the bracket to solve this. 2(3-2)=2*3-2*2. Removing the brackets means to multiply the terms inside the bracket by the one outside. See if that makes a little sense

4. Lepgirl

Could you do that with the one up their ^ ? :)

5. atjari

-2(6-(9/2)x)=-2*6-2*(-9/2)x Nw do u get t?

6. atjari

@Lepgirl

7. Lepgirl

Is that the answer?

8. atjari

No. I didnt simplify t yet.

9. atjari

I hav removed the bracket. see f u cn simplify t. If u cnt tel me.

10. Lepgirl

I can't figure out the answer after simplifying . ): I'm not good at this .

11. atjari

what do u get when u multiply -2 by 6?

12. Lepgirl

-12

13. atjari

what do u get when u multiply -9x/2 by -2

14. Lepgirl

i don't know how to do the 9x/2 part

15. Lepgirl

wait 9x/2 would that be 18x?

16. atjari

17. Lepgirl

So 18x/2 = 9 x is the answer?

18. atjari

combine both ur answers. that is -12+9x

19. Lepgirl

answer is -12 + 9x

20. atjari

ya

21. Lepgirl

here is another. -4/5(3/5x -1)

22. atjari

vat do u get as the answer?

23. Lepgirl

can u do the steps again for this question

24. atjari

|dw:1331706869030:dw|

25. atjari

Say u need to multiply 2/3 by 5. First multiply 2 by 5. U vl get 10. Nw divide 10/3. See if u get a whole number if u do divide. If so write t. If nt leave the fraction as it is. See if that makes a little sense.

@Lepgirl

27. Lepgirl

So what is the simplified answer? :)

28. atjari

I hav posted the answer for ur actual question in my drawing. this I told to giv an idea on multiplying a fraction by a number.

29. Lepgirl

It makes sense.

30. Lepgirl

1 more. :) 7(-1/2x + 1/2)

31. atjari

giv t a try nd tel me vat u get. I vl correct if u get t wrong.

32. Lepgirl

okay :)

33. Lepgirl

hard >.< ):

34. atjari

35. Lepgirl

10.5

36. Lepgirl

whats the answer? :))

37. atjari

|dw:1331708102190:dw|

38. Lepgirl

39. atjari
