Question

1|12+5|18= 1|2+3|4= 1|2+2|3= решите

Answer 1

$\frac{1}{12} + \frac{5}{18} = \frac{3}{36} + \frac{10}{36} = \frac{13}{36} , \\ \\ \frac{1}{2} + \frac{3}{4} = \frac{2}{4} + \frac{3}{4} = \frac{5}{4} = 1 \frac{1}{4}, \\ \\ \frac{1}{2} + \frac{2}{3} = \frac{3}{6} + \frac{4}{6} = \frac{7}{6} = 1 \frac{1}{6}.$

Answer 2

$\frac{1}{12} + \frac{5}{18} = \frac{3}{36} + \frac{10}{36} = \frac{13}{36} \\ \\ \frac{1}{2} + \frac{3}{4} =0.5+0.75=1.25 \\ \\ \frac{1}{2} + \frac{2}{3} = \frac{3}{6} + \frac{4}{6} = \frac{7}{6} =1 \frac{1}{6}$
