Aligning the numbers vertically: Align the numbers vertically by their decimal points for subtraction.We need to subtract 0.883 from 47.3. To do this, we write the numbers one under the other, making sure to align the decimal points:\begin{align*}
&47.3 \
- &0.883
\end{align*}We notice that 47.3 has only one decimal place, so we can add zeros to make the subtraction easier:\begin{align*}
&47.300 \
- &0.883
\end{align*}
