The error is that -2 times -5 is 10 not -10. Then carry on from there because that error meant the rest is wrong as well.
Answer:
18
Step-by-step explanation:
I did my method that I was taught but if you do (-5) - (-2), you get 3. So you subtract 39 by the -21 to get 18.
could you specify your question a bit more?
The fraction is 2/6
This is because there are 6 total sections in the shape (6 becomes denominator) and 2 colored in sections (2 becomes the numerator)
