To divide fractions, find the reciprocal of the divisor fraction (flip the positions of the numerator and denominator) then change the division sign to a multiplication sign. In our case, we'll do:
[tex] \frac{2}{3} * \frac{1}{4}[/tex]
Just multiply the numerators and denominators as seen to get the product of 2/12, which simplifies to 1/6.
