we know that
The quotient of a fraction by a whole number is the same that multiply the fraction by the reciprocal of the whole number
so

Part 1) 1/4 divided by 2

Part 2) 2/3 divided by 6

Simplify

this is the equation of a line in slope intercept form with a slope of 1/4 and a y intercept of -5
For this case we must find the perimeter of the fence, in a circular way, knowing that the perimeter of a circle is given by:

Where "r" represents the radius of the circle, in this case 
Substituting in the perimeter equation we have:

Rationalizing we have:

Taking out common factor
