[tex]a) \frac{7}{100} + \frac{7}{10} = \frac{7}{100} + \frac{7*10}{10*10} = \frac{7+70}{100} = \frac{77}{100} \\ \\ b) \frac{7}{10} + \frac{70}{100} = \frac{7*10}{10*10}+ \frac{70}{100}= \frac{70+70}{100}= \frac{140}{100} \\ \\ c)\frac{1}{10} + \frac{17}{100} = \frac{1*10}{10*10} + \frac{17}{100}= \frac{10+17}{100} = \frac{27}{100} \\ \\ d) \frac{1}{1} + \frac{4}{00} =\frac{1*100}{1*100} + \frac{4}{100} = \frac{100}{100} + \frac{4}{100} = \frac{104}{100} \\ \\[/tex]

[tex]e) \frac{11}{100}+ \frac{8}{10} = \frac{11}{100}+\frac{8*10}{10*10} =\frac{11+80}{100} = \frac{91}{100} [/tex]
