Answer:

90/7

Explanation:

So first things first, you can convert each mixed number into top-heavy fractions, which makes it much easier.

For -3 6/7, you do 7×(-3) which is-21, then -21-6 which is -27. -27 is the numerator of your fraction. The denomintor will be the same (7)

So now you have your first top heavy fraction which is -27/7

Same withthe other fraction:

3×-3= -9----> -9 - 1 = -10 -----> so the second fraction is -10/3

Now you can multiply them

-27/7 × -10/3

First multiply the numerators:

-27 × -10 = 270

Then multiply your denominators:

-7 × -3 = 21

So your answer will be 270/21, but you can still simplify it by diving the numerator and denominator both by 3:

270÷3 = 90

21 ÷ 3 = 7

So your final answer will be 90/7
