Penjelasan dengan langkah-langkah:
1)
[tex] = \frac{3}{5} + 1 \frac{2}{3} \times \frac{4}{5} [/tex]
[tex] = \frac{3}{5} + \frac{ \cancel5}{3} \times \frac{4}{ \cancel5} [/tex]
[tex] = \frac{3}{5} + \frac{4}{3} [/tex]
[tex] = \frac{9 + 20}{15} [/tex]
[tex] = \frac{29}{15} [/tex]
[tex] = \bold{1 \frac{14}{15}} [/tex]
2)
[tex] = \frac{24}{10} \div \frac{3}{10} \times 2 \frac{1}{2} [/tex]
[tex] = \frac{ \cancel{24}^{12} }{ \cancel{10}} \times \frac{ \cancel{10}}{3} \times \frac{5}{ \cancel{2}^{1} } [/tex]
[tex] = \frac{60}{3} [/tex]
[tex] = \bold{20}[/tex]
