Question

помогите пожалуйстааааааааа

Answer 1

$1)  frac{3}{5} = frac{3*6}{5*6} = frac{18}{30}   frac{5}{6} = frac{5*5}{6*5} = frac{25}{30}$

$2)  frac{6}{11} = frac{6*9}{11*9} = frac{54}{99}  frac{4}{9} = frac{4*11}{9*11} = frac{44}{99}$

$3)  frac{5}{6} = frac{5*11}{6*11} = frac{55}{66}   frac{4}{11} = frac{4*6}{11*6} = frac{24}{66}$

$4)  frac{7}{18} = frac{7}{18}   frac{1}{6} = frac{1*3}{6*3} = frac{3}{18}$

$5)  frac{9}{13} = frac{9*5}{13*5} = frac{45}{65}   frac{4}{5} = frac{4*13}{5*13} = frac{52}{65}$

$6)  frac{5}{7} = frac{5*4}{7*4} = frac{20}{28}   frac{3}{4} = frac{3*7}{4*7} = frac{21}{28}$

$6)  frac{2}{15} = frac{2}{15}   frac{1}{3} = frac{1*5}{3*5} = frac{5}{15}$

$8)  frac{5}{8} = frac{5}{8} frac{3}{4} = frac{3*2}{4*2} = frac{6}{8}$
