Question

найдите значение разности 1) 2 1/2- 3 1/3; 3)5 7/8-(-2 5/12) 5)3 9/6- 4 11/24

Answer 1

$1)2frac{1}{2}-3frac{1}{3}=frac{5}{2}-frac{10}{3}=frac{5*3-10*2}{6}=-frac{5}{6}$

$3)5frac{7}{8}-(-2frac{5}{12})=frac{47}{8}+frac{29}{12}=frac{47*3+29*2}{24}=frac{199}{24}=8frac{7}{24}$

$5)3frac{9}{6}-4frac{11}{24}=frac{27}{6}-frac{107}{24}=frac{27*4-107}{24}=frac{1}{24}$
