Prime divided by Prime..

Number Theory Level 1

$\begin{aligned} 3/2 &=& 1.5 \\ 5/2 &=& 2.5 \\ 5/3 &=& 1.6666\ldots \\ 7/3&=& 2.3333 \ldots \end{aligned}$

The above shows all equations of ratios of 2 distinct prime numbers. Is it true that the ratio of 2 distinct prime numbers is never an integer?
