# Fractions in Latex

I typed instruction below into a TeX document and the fraction came out smaller than the rest of the equation. Is there any way of making the b, c and d the same size as the a?

$a = \frac{b}{c+d}$

• inline math is designed to fit into a paragraph without changing the baseline spacing, you could use \dfrac from amsmath but if using large expressions it is better to make the whole expression a display and change $...$ to $..$ – David Carlisle Nov 19 '14 at 13:09
• If you want an inline fraction bigger than the default \textstyle fraction, you can use the nccmath  package: it defines an \mfrac command (‘medium-sized fraction’) – about 80 % of \display style. – Bernard Nov 19 '14 at 15:03

$a = {\displaystyle\frac{b}{c+d}}$

or, after loading amsmath,
$a = \dfrac{b}{c+d}$
