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
