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

Re: Dividing Fractions


In mathematics, you don't understand things. You just get used to them.
Probability is the most important concept in modern science, especially as nobody has the slightest notion what it means.
90% of mathematicians do not understand 90% of currently published mathematics.
