56/7 the set or sets of number to which each real number belongs

First, we need to get the equivalent of the fraction that is given:56/7 is equivalent to 8Then we need to describe is 8 belong to the family of a real number? Since the decimal or the equivalent of the decimal is the whole number so it belongs to the family of real numbers. And stated that it is a Real Number, Rational Number, Whole Number, Counting Number, and Integer. The real number represented by symbol R and it is a value that represents along with a line. A rational number can be expressed as a ratio between 2 numbers and when it is written as a decimal it cannot be written as a simple fraction because there is not a finite number of numbers and the number of decimal would go on forever without repeating.

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.
