Question

Выполните сложение:
3/4+2/3
3/10+2/15
4/9+1/6
7/15+3/40

Answer 1

$frac{3}{4} + frac{2}{3}= frac{9+8}{12} = frac{17}{12} = 1 frac{5}{12}$
$frac{3}{10} + frac{2}{15} = frac{9+4}{30} = frac{13}{30}$
$frac{4}{9} + frac{1}{6} = frac{8+3}{18} = frac{11}{18}$
$frac{7}{15} + frac{3}{40} = frac{56+9}{120} = frac{65}{120} = frac{13}{24}$
