$= 6 \frac{6}{25}$ $=6 6/25$

so first we convert to improper fractions,

$7 \frac{4}{5} \div 1 \frac{1}{4}$ $7 4/5 div 1 1/4$

$= \frac{39}{5} \div \frac{5}{4}$ $=39/5 div 5/4$

dividing by a fraction is the same as multiplying by the inverse of the fraction so,

$= \frac{39}{5} \cdot \frac{4}{5}$ $=39/5 * 4/5$

so simplifying,

$= \frac{39 \cdot 4}{25}$ $=(39*4)/25$

$= \frac{156}{25}$ $=156/25$

turning back into a mixed fraction,

$= 6 \frac{6}{25}$ $=6 6/25$
