Nomor 1.
[tex] \sf\frac{14}{15} - \frac{3}{5} - \frac{3}{10} \\ [/tex]
[tex] \sf = \frac{28}{30} - \frac{18}{30} - \frac{9}{30} \\ [/tex]
[tex] \sf = \frac{28 - 18 - 9}{30} \\ [/tex]
[tex] \sf = \frac{1}{30} \\ [/tex]
Nomor 2.
[tex] \sf\frac{3}{8} + \frac{5}{6} - \frac{2}{3} \\ [/tex]
[tex] \sf = \frac{9}{24} + \frac{20}{24} - \frac{16}{24} \\ [/tex]
[tex] \sf = \frac{9 + 20 - 16}{24} \\ [/tex]
[tex] \sf = \frac{13}{24} \\ [/tex]
Penjelasan dengan langkah-langkah:
nomor 1
[tex] \frac{14}{15} - \frac{3}{5} - \frac{3}{10} = \frac{28}{30} - \frac{18}{30} - \frac{9}{30}[/tex]
[tex] \frac{14}{15} - \frac{3}{5} - \frac{3}{10} = \frac{10}{30} - \frac{9}{30} [/tex]
[tex] \frac{14}{15} - \frac{3}{5} - \frac{3}{10} = \frac{1}{30} [/tex]
nomor 2
[tex] \frac{3}{8} + \frac{5}{6} - \frac{2}{3} = \frac{9}{24} + \frac{20}{24} - \frac{16}{24}[/tex]
[tex] \frac{3}{8} + \frac{5}{6} - \frac{2}{3} = \frac{29}{24} - \frac{16}{24} [/tex]
[tex] \frac{3}{8} + \frac{5}{6} - \frac{2}{3} = \frac{13}{24} [/tex]
