\(\displaystyle{ \frac{12}{5}}\), \(\displaystyle{ \frac{3}{8}}\), \(\displaystyle{ \frac{5}{6}}\), \(\displaystyle{ \frac{32}{15}}\), \(\displaystyle{ \frac{2}{7}}\), \(\displaystyle{ 1\frac{8}{9}}\)


Proszę o szybko odp. z góry thx.

\(\displaystyle{ \frac{12}{5}=2\frac{2}{5}=2,4}\)
\(\displaystyle{ \frac{3}{8}=0,375}\)
\(\displaystyle{ \frac{5}{6}=\frac{3}{6}+\frac{2}{6}=0,5+\frac{1}{3}=0,8(3)}\)
przy \(\displaystyle{ \frac{2}{7}}\) skorzystaj z kalkulatora
\(\displaystyle{ \frac{32}{15}=2\frac{2}{15}=2\frac{12}{90}=2\frac{1,2}{9}=2,1(3)}\)
\(\displaystyle{ 1\frac{8}{9}=1,(8)}\)
