tolong dijawab memakai cara dengan benar!! JADIKAN PECAHAN PERSEN,PECAHAN DESIMAL,DAN PECAHAN BIASA

1. a. Pecahan persen
[tex]70 \: \% + 1.3 + \frac{3}{5} \\ = \frac{70}{100} + \frac{13}{10} + \frac{3}{5} \\ = \frac{70}{100} + \frac{130}{100} + \frac{60}{100} \\ = 70\% + 130\% + 60\% \\ = 260\%[/tex]
b. Pecahan desimal
[tex]70\% + 1.3 + \frac{3}{5} \\ = \frac{70}{100} + \frac{13}{10} + \frac{6} {10} \\ = 0.7 + 1.3 + 0.6 \\ = 2.6[/tex]
c. Pecahan biasa
[tex]70\% + 1.3 + \frac{3}{5} \\ = \frac{70}{100} + \frac{13}{10} + \frac{3}{5} \\ = \frac{7}{10} + \frac{13}{10} + \frac{6}{10} \\ = \frac{26}{10} [/tex]
2. a. Pecahan persen
[tex]0.75 + 150\% + \frac{1}{2} \\ = \frac{75}{100} + \frac{150}{100} + \frac{50}{100} \\ = 75\% + 150\% + 50\% \\ = 275\%[/tex]
b. Pecahan desimal
[tex]0.75 + 150\% + \frac{1}{2} \\ = \frac{75}{100} + \frac{150}{100} + \frac{50}{100} \\ = 0.75 + 1.5 + 0.5 \\ = 2.75[/tex]
c. Pecahan biasa
[tex]0.75 + 150\% + \frac{1}{2} \\ = \frac{75}{100} + \frac{150}{100} + \frac{50}{100} \\ = \frac{275}{100} [/tex]
3. a. Pecahan persen
[tex]1 \frac{1}{8} + 0.375 + 87.5\% \\ = \frac{9}{8} + \frac{375}{1000} + \frac{87.5}{100} \\ = \frac{1125}{1000} + \frac{375}{1000} + \frac{875}{1000} \\ = \frac{112.5}{100} + \frac{37.5}{100} + \frac{87.5}{100} \\ = 112.5\% + 37.5\% + 87.5\% \\ = 237.5\%[/tex]
b. Pecahan desimal
[tex]1 \frac{1}{8} + 0.375 + 87.5\% \\ = \frac{9}{8} + \frac{375}{1000} + \frac{87.5}{100} \\ = \frac{1125}{1000} + \frac{375}{1000} + \frac{87.5}{100} \\ = 1.125 + 0.375 + 0.875 \\ = 2.375[/tex]
c. Pecahan biasa

[tex]1 \frac{1}{8} + 0.375 + 87.5\% \\ = \frac{9}{8} + \frac{375}{1000} + \frac{87.5}{100} \\ = \frac{1125}{1000} + \frac{375}{1000} + \frac{875}{1000} \\ = \frac{2375}{1000} [/tex]
