1. [tex]\frac{2}{1}*\frac{5}{27}=\frac{2*5}{1*27}=\frac{10}{27}[/tex]
2. [tex]\frac{3}{11}* \frac{2}{1}= \frac{3*2}{11*1} =\frac{6}{11}[/tex]
3. [tex]\frac{5}1}* \frac{2}{6} =\frac{5*2}{1*6} =\frac{10}{6}[/tex]
4. [tex]\frac{13}{1}* \frac{12}{15} =\frac{13*12}{1*15}= \frac{156}{15}[/tex]
5.[tex]\frac{2}{1}* \frac{2}{3}= \frac{2*2}{1*3}= \frac{4}{3}[/tex]
6. [tex]\frac{5}{2}* \frac{11}{1} =\frac{5*11}{2*1}= \frac{55}{2}[/tex]
7. [tex]\frac{26}{1}* \frac{7}{10} =\frac{26*7}{1*10}= \frac{182}{10}[/tex]
8. [tex]\frac{4}{21}* \frac{7}{1}= \frac{4*7}{21*1} =\frac{28}{21}[/tex]
