The cost of the pen and pencil are given we have to find which cost more

so, here

$16 \frac{3}{5} and4 \frac{3}{4}$

at first we take the LCM in improper fraction

$\frac{83}{5} and \frac{19}{4} \\ \\ the \: lcm \: is \: 20 \: now \: we \\ \frac{83}{5} \times \frac{1}{4} and \frac{19}{4} \times \frac{1}{5} \\ \frac{83}{20} - \frac{19}{20} \\ = \frac{64}{20}$

• The pen cost more by 83/20
