The water level of a lake rose by 1 2/3 in. during a 3 1/3 week-long wet spell. Simplify the complex fraction below to find the average rate at which the water level changed every week.

Given that,

The water level of a lake rose by 1 2/3 in. during a 3 1/3 week-long wet spell. We need to find the average rate at which the water level changed every week. It is a problem based on the concept of ratio. So,

So, the average rate at which the water level changed every week is 1/2 inches/week.

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.
