What would the mixed number 6/11 round to

6/11 = 0.545454..

= 0.55  rounded to nearest hundredth

Factor both the numerator and denominator down to prime factors:

6 = 2 * 3

11 is a prime number, it cannot be prime factorized

Calculate the greatest common factor, GCF (also called greatest common divisor, GCD), by taking all the common prime factors of the numerator and denominator, by the lowest powers:

gcd (2 * 3; 11) = 1

Fraction's numerator and denominator are coprime numbers (no common prime factors), so the fraction cannot be reduced (simplified).
Rewrite result:

6 ÷ 11 = 0.545454545455 as a decimal number.

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.
