2. 12,5-3/4 =
[tex]1. \: \: \frac{12}{5} - 1.2 = \frac{12}{5 } - \frac{12}{10} \\ \\ = \frac{12}{5} - \frac{6}{5} = \frac{6}{5} = 1 \frac{1}{5} [/tex]
[tex]2. \: \: 12.5 - \frac{3}{4} = \frac{125}{10} - \frac{3}{4} = \frac{25}{2} - \frac{3}{4} \\ \\ = \frac{50 - 3}{4} = \frac{47}{4} = 11 \frac{3}{4} [/tex]
Penjelasan dengan langkah-langkah:
[tex]1. \: \: \frac{12}{5} - 1.2 = \frac{12 {}^{ \times 2} }{5 {}^{ \times 2} } - \frac{12}{10} = \frac{24}{10} - \frac{12}{10} = \frac{ \cancel{12} {}^{6} }{ \cancel{10} \frac{}{5} } = \frac{6}{5} = 1 \frac{1}{5} [/tex]
[tex]2. \: \: 12.5 - \frac{3}{4} = \frac{125}{100} - \frac{3 {}^{ \times 25} }{4 {}^{ \times 25} } = \frac{125}{100} - \frac{75}{100} = \frac{5 \cancel0}{10 \cancel0} = \frac{5}{10}= \frac{1}{2}[/tex]
