Answer
$218_{nine}$
Work Step by Step
Start with rightmost column.
$2$ is less than $3$.
Borrow 1 $nine$ from the $1$ in the next column.
In base ten: $(2+9)-3=8$
Record: $8_{nine}$
$\begin{array}{llll}
& 7 & 1 & 2_{nine}\\
- & 4 & 8 & 3_{nine}\\
-- & -- & -- & --\\
& & & 8_{nine}
\end{array}$
Next column:
$(1-1)=0$ (we borrowed one eight)
0 is less than 8... borrow 1 nine from the 7
$(0+9)-8=1$
Record the $1$.
$\begin{array}{llll}
& 7 & 1 & 2_{nine}\\
- & 4 & 8 & 3_{nine}\\
-- & -- & -- & --\\
& & 1 & 8_{nine}
\end{array}$
Next column:
$7-1=6$ (one was borrowed)
$6-4=2$
Record the 2.
Result: $218_{nine}$
