\(3,25=3\dfrac{1}{4}\\ 4,125=4\dfrac{1}{8}\\ 6,15=6\dfrac{3}{20}\\ 1,25=1\dfrac{1}{4}\)
\(0,75=\dfrac{75}{100}=\dfrac{75:25}{100:25}=\dfrac{3}{4}\\ 0,8=\dfrac{8}{10}=\dfrac{8:2}{10:2}=\dfrac{4}{5}\\ 2,15=\dfrac{215}{100}=\dfrac{215:5}{100:5}=\dfrac{43}{20}\)
A) \(0,75=\dfrac{75}{100}=\dfrac{75:25}{100:25}=\dfrac{3}{4}\)
B) \(0,8=\dfrac{8}{10}=\dfrac{8:2}{10:2}=\dfrac{4}{5}\)
C) \(2,15=\dfrac{215}{100}=\dfrac{215:5}{100:5}=\dfrac{43}{20}\)
