A = LW
A = 2/3 * 3/4
A = 6/12 = 1/2 miles^2
You need 250-116=$134. At $15 a day this is 134/15=8.93 days approx. After 9 days you will reach $251.
Factor the numerator and factor the denominator.

Then you divide the numerator and the denominator by the common factor to reduce the fraction.
Well, we're just simplifying the fraction.
(2x^2)(y/4).
(2yx^2)/4.
When powers of the same base are being divided, subtract. The numbers are just plain fractions. 6/3 = 2 and 4/16 = 1/4. x^4/x^2 = x^2 and y^2/y = y.
Edit:
2/4 is 1/2.
(yx^2)/2.
