Suppose p/q, r/s, and t/u represent three rational numbers. If p/q is greater than r/s, and r/s is greater than t/u, compare p/q and t/u. Explain your reasoning.

p/q (< or >) t/u. On a number line, p/q is to the (right or left) of r/s, and r/s is to the (right or left) of t/u. So, p/q is to the (right or left) of t/u. ​
