Ask the student a question, and give any hints about how they should answer this part.

Convert $(\;\var{n}\;)_{10}$ from decimal to base $\var{m}$ notation.

$(\;\var{n}\;)_{10}\;=\;(\;$ Gap 0. $\;)_\var{m}$

Convert $(\;\var{nt}\;)_\var{m}$ from base $\var{m}$ to base ${10}$ notation.

$(\;\var{nt}\;)_\var{m}\;=\;(\;$ Gap 1. $\;)_{10}$
