Problem

How many whole numbers lie in the interval between $\frac{5}{3}$ and $2\pi$ ?

$\text{(A)}\ 2 \qquad \text{(B)}\ 3 \qquad \text{(C)}\ 4 \qquad \text{(D)}\ 5 \qquad \text{(E)}\ \text{infinitely many}$

Solution

The smallest whole number in the interval is $2$ because $5/3$ is more than $1$ but less than $2$ . The largest whole number in the interval is $6$ because $2\pi$ is more than $6$ but less than $7$ . There are five whole numbers in the interval. They are $2$ , $3$ , $4$ , $5$ , and $6$ , so the answer is $\boxed{\text{(D)}\ 5}$ .
