(2.)[tex](i)=\bf\frac{3}{5}[/tex][tex](ii)=\bf\frac{4}{5}[/tex][tex](iii)=\bf\frac{1}{4}[/tex]
(3.)(i) = 50%(ii) = 75%(iii) = 5 %
Penjelasan dengan langkah-langkah:(1.) Pecahan, ubah penyebut jd 100[tex](i)\:\:\frac{1}{4}=\frac{1\times25}{4\times25}=\frac{25}{100}\because\frac{ab}{100}=0,ab\therefore\frac{25}{100}=\bf0,25[/tex][tex](ii)\:\:\frac{1}{2}=\frac{1\times50}{2\times50}=\frac{50}{100}=\frac{5}{10}\because\frac{a}{10}=0,a\therefore\frac{5}{10}=\bf0,5[/tex][tex](iii)\:\:\frac{3}{4}=\frac{3\times25}{4\times25}=\frac{75}{100}\because\frac{ab}{100}=0,ab\therefore\frac{75}{100}=\bf0,75[/tex]
(2.) Menjadi pecahan biasa[tex](i)\because0,a=\frac{a}{10}\therefore0,6=\frac{6}{10}=\frac{6\div2}{10\div2}=\bf\frac{3}{5}[/tex][tex](ii)\because0,a=\frac{a}{10}\therefore0,8=\frac{8}{10}=\frac{8\div2}{10\div2}=\bf\frac{4}{5}[/tex][tex](iii)\because0,ab=\frac{ab}{100}\therefore0,25=\frac{25}{100}=\frac{25\div25}{100\div25}=\bf\frac{1}{4}[/tex]
(3.) Menjadi persen[tex](i)\:\:\frac{1}{2}=\frac{1\times50}{2\times50}=\frac{50}{100}\because\frac{ab}{100}=ab\%\therefore\frac{50}{100}=\bf50\%[/tex][tex](ii)\:\:\frac{3}{4}=\frac{3\times25}{4\times25}=\frac{75}{100}\because\frac{ab}{100}=ab\%\therefore\frac{75}{100}=\bf75\%[/tex][tex](iii)\because\frac{ab}{100}=ab\%\therefore\frac{5}{100}=\bf5\%[/tex]
