a, 0,5 = \(\dfrac{5}{10}\); 0,71 = \(\dfrac{71}{100}\); 1,348 = \(\dfrac{1348}{1000}\); 49,16 = \(\dfrac{4916}{100}\)
b, \(\dfrac{3}{5}\) = \(\dfrac{3\times2}{5\times2}\) = \(\dfrac{6}{10}\); \(\dfrac{7}{25}\) = \(\dfrac{7\times4}{25\times4}\) = \(\dfrac{28}{100}\); \(\dfrac{6}{125}\) = \(\dfrac{6\times8}{125\times8}\)= \(\dfrac{48}{1000}\)
\(\dfrac{7}{4}\) = \(\dfrac{7\times25}{4\times25}\) = \(\dfrac{175}{100}\)
\(\dfrac{1}{4}\) = 0,25
\(\dfrac{3}{4}\) = 0,75
\(\dfrac{5}{7}\) ≈0,714
\(\dfrac{12}{28}\) ≈ 0,43
\(\dfrac{35}{105}\)≈ 0,33
\(a.\)
\(0.3=\dfrac{3}{10}\)
\(0.72=\dfrac{72}{100}\)
\(1.5=\dfrac{15}{10}\)
\(9.347=\dfrac{9347}{1000}\)
\(b.\)
