How do you write a fraction in overleaf?
As you may have guessed, the command \frac{1}{2} is the one that displays the fraction. The text inside the first pair of braces is the numerator and the text inside the second pair is the denominator. Also, the text size of the fraction changes according to the text around it. You can set this manually if you want.
What does frac mean in math?
Frac() returns the fraction to the right of the decimal point of x, where x is a real number. The fraction is defined in such a way that Frac(x ) + Floor(x ) = x. In simple terms this means that the fractional part of a positive number is the difference between the number (x) and the integer that precedes it.
How do I write denominators in LaTeX?
Fractions and binomial coefficients of math equations in LaTeX are written using the \frac and \binom command respectively. We use the \frac command to display fractions. The expression between the first pair of brackets is the numerator and in the second is the denominator.

What is the difference between [math]\\dfrac37 and \frac37?
The difference between the “frac”s is the size of the resulting fraction. The “d” stands for “display” and produces a larger result: [math]\\dfrac37[/math] The “t” stands for “text” and produces a smaller result more appropriate for fractions within running text: [math]\frac37[/math]
