### Dividing Fractions

I am trying to help my daughter divide fractions  the problem is 2/3 divided by n = 3/4.  I am having a terrible time figuring it out and  of course she has no book for examples.  Can anyone help?  Thanks so much:)

### Re: Dividing Fractions

for teaching, figuring it out like

(2/3) / n = (3/4)
(2/3) /= (3/4) *n
(2/3) / (3/4) = n
n= (2/3) / (3/4)
n= (2/3) * (4/3)
n= (2*4)/(3*3)
n= 8/9

all you need to do , is to put the divisor up side down and multiply

(2/3) / (3/4) = [(2/3) / (3/4)] x [(4/3) / (4/3)] = (2/3) x (4/3)  = 8/9

In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.
