Question 11539
Q. is  4(-3/5)  -  3(1/4 )  divided by [2(-3/5)]

soln:

First open the big bracket therefore it becomes

4(-3/5)  - 3(1/4)  divided by (-6/5)

Now remove the small brackets,  i.e.:

-12/5 - 3/4  devided by -6/5

You can write the above as given below just by pressing 
underscore key for showing the divn. line  or

-(12/5 + 3/4)
_____________     
 - 6/5


cancel the (-) sign on top and bottom
and by finding LCM of top terms we group them together, thus

48 + 15 = 63/20 divided by 6/5

Now use multiply instead of division , that means the terms 
will change places on top and bottom of '6/5'  i.e

63/20 multiply by 5/6  after cancellation we get

63/24 which is the ans
