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

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

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

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