Oblicz 0,96: 3 i 6/5

[supergolonka]

Oblicz: \(0,96: 3\frac{6}{5}\).

[supergolonka]

Liczymy \[0,96: 3\frac{6}{5}=\frac{96}{100}:\frac{21}{5}=\frac{96}{100}\cdot \frac{5}{21}=\frac{24}{25}\cdot \frac{5}{21}=
\frac{8}{5}\cdot \frac{1}{7}=\frac{8}{35}.\]

Odpowiedź: \(\frac{8}{35}\)

Liczymy \[0,57: 2\frac{8}{15}=\frac{57}{100}:\frac{38}{15}=\frac{3\cdot 19}{100}\cdot \frac{15}{2\cdot 19}=\frac{3}{20}\cdot \frac{3}{2}=\frac{9}{40}.\]

Odpowiedź: \(\frac{9}{40}\)
