$\frac{8}{3} \times \frac{2}{12}=$

Sep 27, 2013the title says it all, both \dfrac {a} {b} and \frac {a} {b} make fractions, so what is the difference between the two? Oct 8, 2010if you want the numerator on top of the denumerator, and have it appear smaller, the way it typically does in inline math mode as opposed to displayed math style, then use \tfrac{x}{y} (requires. \frac is a latex-only command that builds on the \over macro to provide something that's much less likely.

${ \frac{\fam0 a}{b} }$ for my purposes, should such an issue arise, it is easily resolved by using \frac and so, while this example illustrates a shortcoming of \over and the need for something more robust, it. It is nearly always best to use the slashed form for fractions in the text: With amsmath or mathtools you can write dfrac instead of frac, but since dfrac is used for inline fractions, it won't change anything for you in math environments.

Dec 8, 2016often it looks better to use \tfrac if you are just wanting a numeric fraction as part of an expression, when the display fraction can look a bit spacey. Conversely if the fraction is already a. Sep 12, 2018this runs fine without any errors but i would like to use the regular \frac function because it is neater for the particular problem.

The \scaleleftright[maxwidth]{left-delim}{term}{right-delim} macro provides scalable (not extensible) delimiters without forcing vertical height symmetry about \frac s. Your question is basically about mathjax usage in websites (such as math.se), but fortunately, \frac or \dfrac command (for 'better' fractions) work with mathjax
