Hey Anonymous,

 

$$\frac{-7}{3}-\frac{5}{-6} = -\frac{7}{3}--\frac{5}{6} = -\frac{7}{3}+\frac{5}{6} = -\frac{14}{6}+\frac{5}{6} = -\frac{9}{6} = -\frac{3}{2}$$

First I put the minus signs in front of the fractions,

Minus minus is the same as plus so I changed that

I made both denominators of the fractions the same by multiplying both the nominator and denominator of $$\frac{7}{3}$$ by 2

 

Then I added both fractions

And finally I simplified the fraction

p.s. please use / instead of % on the forum. % can be very confusing because it is usually used as 'percentage'
