Answer
$2\frac{3}{5}$
Work Step by Step
$3\frac{1}{4}\div1\frac{1}{4}$
= $\frac{13}{4}\div\frac{5}{4}$
= $\frac{13}{4}\times\frac{4}{5}$(To divide two fractions, multiply the first fraction by the reciprocal of the divisor (the second fraction)).
= $\frac{13\times4}{4\times5}$ (Multiply the nominator and denominator)
= $\frac{13\times1}{1\times5}$
=$\frac{13}{5}$
= $2\frac{3}{5}$
