If you draw a rectangle divided up into eight even parts, and label them each as 1/8, then you can show your work for how you double it. You do this by "coloring" one in, and then doing the same for a second piece (but color that one in a different way). You can visually double an eighth in that way.
Or, you can simply multiply by 2 to double 1/8:
1/8x2/1=2/8
Answer:
I think it is 53.3%. I DEEPLY apologize if i'm wrong. <3 Good luck!
The equation for the circumference is 2*pi*radius
if you are given the circumference then divide both sides by pi
that is because the diameter is 2 times the radius
so you can rearrange the equation to
C = pi * 2 * r
C = pi * d
divide both sides by pi
C/pi = d
Hope this helps :)
4.7, because its tenths place is highest
