Construct a 90 degree angle isosceles triangle which will have equal sides and then divide the base into 9 equal parts joining the parts by lines to the apex of the trangle. Each line represents 10 degrees and 8 lines will equal to 80 degrees.
The radius of a circle is equal to half of it's diameter. To convert the diameter into the radius, simply divide it by two.For example: if the diameter is 10, then the radius would be 5
I say yes. 8/10 divide by 2=4/5

Use a protractor and divide it into 36 degree wedges.
By changing it into a regular 10 sided decagon
A tenth means that you divide something into 10 equal parts. A hundredth means that you divide something into a hundred equal parts. If you divide something into MORE parts, each part will be SMALLER.
A circle is 360 degrees. If they are equal parts, they are 36 degrees apiece, or 144 degrees.

10 and 2/3 x 6 = 64
To get the idea of percentage, remember this, The question boils down to this. What would be the value if you can divide 6.20 into 100 equal parts and take 10 of those equal parts The answer is (6.20/100) x 10 = 0.0620 x 10 = 0.620

start with a little V on the top and put a little line in it
Fractions are a part of the whole. So 1/2 is a half of something. A circle divided into 10 parts, each part is 1/10th of the whole circle.
By marking out 10 arcs of 36 degrees around its circumference and joining them to the centre of the circle.
