Greta made a design with squares. she colored 8 out of the 12 squares blue. what fraction of the squares did she color blue? you

2/3 because 8/12 divided down is 4/6 which reduced again is 2/3

She colored 2/3 of the squares blue.
To get 8/12 you would look for the greatest common factor of both 8 and 12.
We know that 4x2=8 and 4x3=12. So the common factor would be 4 because both numbers go into  4 evenly. Then you would divide both the numerator (8) and denominator(12). 8/4=2 and 12/4=3 so your answer is 2/3  
It would look like this:
=

B.-2,3 because it is touch the -3 i think that the answer
