3
Work Step by Step
$\frac{3}{4} \div \frac{1}{4}$
Change division to multiplication. Invert $\frac{1}{4}$ and write its reciprocal.
$\frac{3}{4}$ * $\frac{4}{1}$ = $\frac{3*4}{4*1}$ = $\frac{12}{4}$
Since 4 is the greatest common factor of 12 and 4, divide numerator and denominator by 4
So, $\frac{4*3}{4*1}$ = 3
