$1\frac{1}{2}=\frac{1*2+1}{2}=\frac{3}{2}\\\\3\frac{1}{4}=\frac{3*4+1}{4}=\frac{13}{4}\\\\5\frac{1}{2}=\frac{5*2+1}{2}=\frac{11}{2}$

_____________________________________

$\frac{1}{2}=\frac{1*4}{2*4}=\frac{4}{8}\\\\\frac{3}{2}=\frac{3*4}{2*4}=\frac{12}{8}\\\\\frac{3}{4}=\frac{3*2}{4*2}=\frac{6}{8}\\\\\frac{13}{4}=\frac{13*2}{4*2}=\frac{26}{8}\\\\\frac{11}{2}=\frac{11*4}{2*4}=\frac{44}{8}$

$\frac{1}{2}=\frac{1*50}{2*50}=\frac{50}{100}\\\\\frac{3}{2}=\frac{3*50}{2*50}=\frac{150}{100}\\\\\frac{3}{4}=\frac{3*25}{4*25}=\frac{75}{100}\\\\\frac{13}{4}=\frac{13*25}{4*25}=\frac{325}{100}\\\\\frac{11}{2}=\frac{11*50}{2*50}=\frac{550}{100}$
