Answer 1

а) $frac{13}{25} + 0,39 = frac{52}{100} + frac{39}{100} = frac{91}{100} = 0,91$

б) $frac{4}{5} - 0,37 = frac{80}{100} - frac{37}{100} = frac{43}{100} = 0,43$

в) $0,6 + frac{4}{9} = frac{3}{5} + frac{4}{9} = frac{27}{45} + frac{20}{45} = frac{47}{45} = 1 frac{2}{45}$

г) $frac{5}{6} - 0,75 = frac{5}{6} - frac{3}{4} = frac{10}{12} - frac{9}{12} = frac{1}{12}$

67.$x - frac{3}{5} = frac{1}{15}$
$x = frac{1}{15} + frac{9}{15}$
$x = frac{10}{15}$
$x = frac{2}{3}$
