Question

срочно кто знает!!!!!!!!

Answer 1

$frac{24}{25} + frac{3}{5} = frac{1 times 24 + 5 times 3}{25} = frac{39}{25} = 1 frac{14}{25}$

$frac{11}{36} + frac{7}{12} = frac{1 times 11 + 3 times 7}{36} = frac{32}{36} = frac{8}{9}$

$frac{3}{4} + frac{19}{40} = frac{10 times 3 +1 times 19 }{40} = frac{49}{40} = 1 frac{9}{40}$

$frac{5}{6} + frac{31}{42} = frac{7 times 5 + 1 times 31}{42} = frac{66}{42} = frac{11}{7} =$

$1 frac{4}{7}$
