Eight of them.
It equals 80%
To divide a circle into thirteenths, divide it into thirteen equal portions, or pieces.
Only once, there will only be eights parts however you divide it.
3 and 3/8 percent x 2600 = 8775.
0.66 is approximately 2/31/8 = 0.125You can fit 0.66/0.125 = 5 eights in 0.66, but you're left with 7/200 which is too small to divide in eights.
Construct a circle with a 4.5 radius. The circle's circumference is 360 degrees. So mark out 3 by 120 degrees on the circumference and join them to the centre of the circle which will divide the circle into three equal parts.
From the center of the circle, draw like a cross from there.
circle is 2d so, just fold it 15!
1.75 eights is equal to 14.
Not everyone knows ?
A circle has 360 degrees. Divide 360 by 18 and you will find that each equal part of the divided circle is 20 degrees.
