Answer 1

Ответ:

Пошаговое объяснение:

$1+\frac{1}{2} =\frac{2}{2} +\frac{1}{2} =\frac{3}{2}$

$1+\frac{1}{3} =\frac{3}{3} +\frac{1}{3} =\frac{4}{3}$

$1+\frac{1}{4} =\frac{4}{4} +\frac{1}{4} =\frac{5}{4}$

$1+\frac{1}{5} =\frac{5}{5} +\frac{1}{5} =\frac{6}{5}$

$1+\frac{1}{6} =\frac{6}{6} +\frac{1}{6}=\frac{7}{6}$

$1+\frac{1}{7} =\frac{7}{7} +\frac{1}{7}=\frac{8}{7}$

$\frac{3}{2} *\frac{4}{3} =2$

$\frac{2}{1} *\frac{5}{4} =\frac{5}{2}$

$\frac{5}{2} *\frac{6}{5} =3$

$3*\frac{7}{6} =\frac{21}{6}$

$\frac{21}{6} *\frac{8}{7} =\frac{12}{3} =4$
