A) From the table, the greatest amount of rainfall is 3 1/4 in, and the least amount of rainfall is 3/4 in. The difference between these values is:
[tex]\begin{gathered} 3\frac{1}{4}-\frac{3}{4}= \\ =\frac{13}{4}-\frac{3}{4}=\frac{10}{4} \\ =\frac{10}{4}= \\ =2\frac{1}{2}\text{ in} \end{gathered}[/tex]B) The most common amount of rainfall is 2 3/4 in. If in the last two months the amount of rainfall is 2 3/4 in, then it will fall:
[tex]\begin{gathered} 2\frac{3}{4}+2\frac{3}{4}= \\ =\frac{11}{4}+\frac{11}{4}= \\ =\frac{22}{4}= \\ =5\frac{1}{2}\text{ in} \end{gathered}[/tex]
