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:)

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

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

Welcome to the forum, !mathfun and lostmathmom.

I'm moving this to the Help Me forum ... hopefully you'll still be able to find it. I'll leave a redirect.

Thanks guys, and have fun on the forum.

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
