for example 7/9 / -5/6
the negative sign is in the middle of the fraction not on top or bottom
the negative sign is in the middle of the fraction not on top or bottom

This is a little song my algebra teacher taught us. "Dividing fractions, as easy as pie. Just flip the second and multiply!" so the equation will change to 7/9 • -6/5. When the negative is in the middle, put it to the top and multiply across. You should get -42/45.

to divide fractions you need to multiple by the reciprocal. which means change the division to multiplication and flip the second fraction
so. the reciprocal of -5/6 is -6/5
so,
7/9 * -6/5
now to multiply fractions it's top by top, bottom by bottom.
7*-6=-42, 9*5=45
so 7/9 * -6/5 = -42/45
now simplify, meaning find the largest number that divides both 42 and 45, which is 3!
-42/45=-14/15
so. the reciprocal of -5/6 is -6/5
so,
7/9 * -6/5
now to multiply fractions it's top by top, bottom by bottom.
7*-6=-42, 9*5=45
so 7/9 * -6/5 = -42/45
now simplify, meaning find the largest number that divides both 42 and 45, which is 3!
-42/45=-14/15

you multiply the numerator by the reciprocal of the denominator, and since one is positive and one is negative, the answer will be negative.
7/9 * -6/5 = -42/45
7/9 * -6/5 = -42/45
-
You divide by a fraction by multiplying with the reversed fraction. In your case it's be:
7/9 : -5/6 -> 7/9 · -6/5 -> -14/15
PS: Don't worry, it's the same as -42/45 ^^
7/9 : -5/6 -> 7/9 · -6/5 -> -14/15
PS: Don't worry, it's the same as -42/45 ^^

After using the reciprocal of -5/6, multiply straight across.....7/9 * -6/5 =-63/45
-
7/9 / -5/6 =
-7*6 / 9*5=
-14/15
-7*6 / 9*5=
-14/15
-
This is same as:
7 / ( 9 x (-5/6)) = -7/7.5 = -0.93
7 / ( 9 x (-5/6)) = -7/7.5 = -0.93
