5. 0,75+1/2
2. 12/17 - 10/34=
3. 5/25=.......... (bilangan desimal)
4. 2 4/5=.............( bilangan desimal)
5. 0,75+1/2
Jawab:
[tex]1. \frac{2}{3} +\frac{6}{12} =\frac{8}{12} +\frac{6}{12} =\frac{14}{12} =1\frac{2}{12} =1\frac{1}{6}[/tex]
[tex]2.\frac{12}{17} -\frac{10}{34} =\frac{24}{34} -\frac{10}{34} =\frac{14}{34} =\frac{7}{17}[/tex]
[tex]3.\frac{5}{25} =\frac{5 X4}{25X4} =\frac{20}{100} =0,20[/tex]
4.[tex]2\frac{4}{5} =\frac{14}{5} =\frac{14X2}{5X2} =\frac{28}{10} =2,8[/tex]
5. [tex]0,75+\frac{1}{2} =\frac{75}{100} +\frac{1}{2} =\frac{75}{100}+\frac{50}{100} =\frac{125}{100} =1\frac{25}{100} =1\frac{25:25}{100:25} =1\frac{1}{4}[/tex]
