#### Work Step by Step

Simply put, the first question asks if a number $a$ can be less than itself. Logic tells us the answer is no. The second question asks if a number $a$ can be less than another number $b$. Yes is the answer for obvious reasons. The third question asks if a number $a$ can be less than another number $b$ can be less than another number $c$. This is possible (ex. 1$\lt$2$\lt$3), so the answer is yes.
