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

Dividing by a fraction is the same as muiltiplying by its inverse:

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

Re: Dividing Fractions

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

Re: Dividing Fractions

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