Question 7,8 and 10 me explain it to

Please, please post only ONE question at a time.  The format of 's screen does not lend itself well to discussing more than one question at once.

Draw a shape and color it so that 2/3 of the shape is blue and 1/6 is yellow.
You'd have an easier time here if you were to convert 2/3 to 4/6 (same denominator as 1/6).

Why not draw a circle?  Divide its interior area into 6 equal slices.  You'd color 4 of these slices blue and 1 of them yellow, but would not color the 6th one.

I’ll you if you answer my questions!
