To divide fractions, you want to KFC, which stands for Keep, Flip, Change. That means, Keep the 1st fraction, Flip the 2nd fraction, and Change to a multiplication problem.
-9/10 divided by -6/15
-9/10 * 15/-6
When you are multiplying fractions, you can cancel out common factors as long as you do one from the top with one on the bottom. If you are not sure, you can also multiply straight across (top times top, bottom times bottom) and then reduce at the end.
In this case, the -9 and -6 have a common factor of -3 to cancel out, and the 10 and 15 have a 5 in common. Cancel by divided each by those common factors.
-9/10 * 15/-6
3/2 * 3/2
(3*3)/(2*2) = 9/4
And that is fully reduced.

When dividing fractions, invert the divisor, in this case, -6/15, then multiply the numerators together and the denominators together. Also, a minus multiplied or divided by a minus is a plus:
-9/10 / -6/15
-9/10 * -15/6
-(9 * 15) / (-15 * 6)
-135 / -60
135 / 60
2 1/4
