a) [tex]\frac{1}{8} *32 = \frac{32}{8}=4[/tex]
b) [tex]\frac{3}{5}*25 = \frac{75}{5} =15[/tex]
c) [tex]4\frac{1}{2} : 5 = \frac{9}{2} : 5 = \frac{9}{2} : \frac{5}{1} =\frac{9}{2} * \frac{1}{5} = \frac{9}{10}[/tex]
d) [tex]2\frac{1}{2} + \frac{3}{4} = \frac{5}{2} + \frac{3}{4} = \frac{10}{4} + \frac{3}{4} = \frac{13}{4} = 3\frac{1}{4}[/tex]
