Answer 1

`a) (7)/(100) + (7)/(10) = (7)/(100) + (7*10)/(10*10) = (7+70)/(100) = (77)/(100) \\ \\ b) (7)/(10) + (70)/(100) = (7*10)/(10*10)+ (70)/(100)= (70+70)/(100)= (140)/(100) \\ \\ c)(1)/(10) + (17)/(100) = (1*10)/(10*10) + (17)/(100)= (10+17)/(100) = (27)/(100) \\ \\ d) (1)/(1) + (4)/(00) =(1*100)/(1*100) + (4)/(100) = (100)/(100) + (4)/(100) = (104)/(100) \\ \\`


`e) (11)/(100)+ (8)/(10) = (11)/(100)+(8*10)/(10*10) =(11+80)/(100) = (91)/(100)`
