# Can fractions be written with a one under them and can problems be solved this way

How would you write $\frac{a}{0.1}$?

Are either of these ways acceptable?

$$\frac{\frac{a}{1}}{\frac{\frac{1}{10}}{1}} = \frac{a}{1} \times \frac{1}{\frac{1}{10}}$$ or $$\frac{\frac{a}{1}}{\frac{1}{10}} = \frac{a}{1} \times \frac{10}{1}$$

• You might be interested in learning to post mathematical expressions using MathJax and $\LaTeX$. In any case dividing by one-tenth is the same as multiplying by ten, right? If you are studying fractions at less than a high school level, it would be helpful to your Readers to say so. – hardmath May 12 '16 at 21:23

Both expressions are correct and yield $10a$ in the completely simplified form.
