Is 3pi/2pi a rational number or an irrational number? Explain your reasoning

It is rational

Step-by-step explanation:

The pi terms cancel out when you divide. This is due to the rule x/x = 1 where x is any number you want except x cannot be zero. So replace x with pi and we have pi/pi = 1

Therefore,

(3pi) / (2pi) = (3/2) * (pi/pi)

(3pi) / (2pi) = (3/2) * 1 ... use the rule mentioned above

(3pi) / (2pi) = 3/2

we get a fraction or a ratio of two whole numbers, so this proves that the given expression is rational.
