How are fractions related to division

They're the same thing.

Step-by-step explanation:

Fractions are just a different way of representing divisions, and proof of that, is that the concept of fractions is the same as the concept of division:

, for example, is a fraction that represents the totality of a shape that has been divided into 4 parts.

This different way of representing divisions allows us to work easily with certain numbers (usually decimals) so that our equations and calculations aren't so confusing as they would be if we used decimals instead of fractions.

Fractions are division problems. The line between the top and bottom numbers is just another way of writing the division symbol. The top number is the number being divided up and we call this the numerator. The bottom number is the number we are dividing by and we call it the denominator.

I listed some examples of common fractions below.

step-by-step explanation:

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet
