a)
b) $5\frac{2}{5} = \frac{{5 \times 5 + 2}}{5} = \frac{{27}}{5}$
$4\frac{7}{{10}} = \frac{{4 \times 10 + 7}}{{10}} = \frac{{47}}{{10}}$
$6\frac{{13}}{{100}} = \frac{{6 \times 100 + 13}}{{100}} = \frac{{613}}{{100}}$
c) $\frac{{96}}{{50}} = \frac{{192}}{{100}} = 1,92$
$\frac{{327}}{{300}} = \frac{{109}}{{100}} = 1,09$
$\frac{{204}}{{125}} = \frac{{1632}}{{1000}} = 1,632$
