Answer:

$\frac{-1}{3}$

Step-by-step explanation:

$\frac{-1}{13} - \frac{10}{39}$

Find common denominator for 13 and 39

common denominator is 39

rewrite fractions so they have the same denominator

$\frac{-1}{13} = \frac{-3}{39}$

add them up

$\frac{-3}{39} + \frac{-10}{39} = \frac{-13}{39}$

simplify/ put in the lowest terms

$\frac{-1}{3}$
