Помогите решить 2/3 +1/9 это дроби
3/5+2/7
1/6+3/8
2/3-3/5
5/6-1/4

Answer 1

$frac{2}{3} + frac{3}{9} = frac{6}{9} + frac{3}{9} = frac{9}{9} = 1$

$frac{3}{5} + frac{2}{7} = frac{21}{35} + frac{10}{35} = frac{31}{35}$

$frac{1}{6} + frac{3}{8} = frac{4}{24} + frac{9}{24} = frac{13}{24}$

$frac{2}{3} - frac{3}{5} = frac{10}{15} - frac{9}{15} = frac{1}{15}$

$frac{5}{6} - frac{1}{4} = frac{20}{24} - frac{6}{24} = frac{14}{24} = frac{7}{12}$
