# dfrac no larger than frac

I'm making a compound fraction for a review worksheet. I currently have this:

\begin{multicols}{2}
\begin{enumerate}

\item
Simplify
$\dfrac{\frac{3}{5} + \frac{5}{5x}}{1 - \frac{1}{10x}}$


The problem is that the fractions 3/5 are extremely tiny. If I replace \dfrac with \frac, I see that they are exactly the same. I want the main fraction to be large, and the smaller fractions to be normal. Am I missing a package? Is there a better way to get what I need?

• In display math environment in such simple case both should have the same size. Try difference in \frac{1}{\frac{1}{2}} and \frac{1}{\dfrac{1}{2}}. – Zarko Oct 19 '15 at 18:29
• The outer \dfrac is not doing anything as it is already in display mode, you could use \dfrac for the inner ones, or you could put \Large before the $ – David Carlisle Oct 19 '15 at 18:37 ## 1 Answer Make your choice! nccmath defines a \mfrac command (medium-sized fractions, about 80 % of displaystyle): \documentclass{article} \usepackage{multicol} \usepackage{nccmath} \begin{document} \begin{multicols}{2} \begin{enumerate} \item Simplify \[ \frac{\frac{3}{5} + \frac{5}{5x}}{1 - \frac{1}{10x}} = \frac{\mfrac{3}{5} + \mfrac{5}{5x}}{1 - \mfrac{1}{10x}} = \frac{\dfrac{3}{5} + \dfrac{5}{5x}}{1 - \dfrac{1}{10x}}$
