The simplest commands for writing fractions are \\frac{n}{d}<\/code> and \\dfrac{n}{d}<\/code>, in which “n” is the numerator and “d” is the denominator.<\/p>\n

The \\dfrac<\/code> command is best used when you want to write a large “display” fraction, likely on its own line. If you’re writing a fraction in running text and need it to be close to the same size as the text around it, the \\frac<\/code> command is probably better. If you’re not sure which command to use in any given case, try both and see which size is more appropriate.<\/p>\n
