Szczegółowe wyjaśnienie:
Ułamek zwykły, w którym licznik jest większy lub równy od mianownika nazywamy ułamkiem niewłaściwym. Możemy zapisać taki ułamek w postaci liczby mieszanej, czyli całości i ułamka.
Zgodnie z powyższym:
[tex]a)\\\dfrac{7}{5}=\dfrac{5+2}{5} =\dfrac{5}{5} +\dfrac{2}{5} =1\dfrac{2}{5}\\\\b)\\\dfrac{16}{5} =\dfrac{15+1}{5} =\dfrac{15}{5} +\dfrac{1}{5} =3\dfrac{1}{5} \\\\c)\\\dfrac{78}{5} =\dfrac{75+3}{5} =\dfrac{75}{5} +\dfrac{3}{5} =15\dfrac{3}{5} \\\\d)\\\dfrac{16}{7} =\dfrac{14+2}{7} =\dfrac{14}{7} +\dfrac{2}{7} =2\dfrac{2}{7} \\\\e)\\\dfrac{25}{7} =\dfrac{21+4}{7} =\dfrac{21}{7} +\dfrac{4}{7} =3\dfrac{4}{7} \\\\f)\\\dfrac{38}{7} =\dfrac{35+3}{7} =\dfrac{35}{7} +\dfrac{3}{7} =5\dfrac{3}{7}[/tex]
