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

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