Mathematical Expression

Question

I want to display the following in my thesis document: (1/7) ≤ X < (6/7)

I tried using the command: $\frac{1}{7}$ \leq $X < $\frac{6}{7}$

But I keep getting error messages, such as "missing $ inserted" appointing to the part $\frac{1}{7}$ \leq.

Though it does print out what I want, but it still seems to be wrong somehow. And there is some white space missing between ≤ and X.

Neither $ [ $\frac{1}{7}$ ] \leq $X

nor $ ( $\frac{1}{7}$ ) \leq $X

nor $ { $\frac{1}{7}$ } \leq $X

nor $ $\frac{1}{7}$ \leq $X

were correct.

Can somebody please help? Thanks in advance!

Answer 1

Your problem is that the \leq should be inside the math formula, not outside. Try this:

 $\frac{1}{7} \leq X < \frac{6}{7}$

(this worked fine when making this solution).
