пж помогите мне пж!!!!! даю все баллы​

Answer 1

Ответ:

Пошаговое объяснение:

И) = 5/9 - 8/9 = -3/9 = -1/3

К) = 3/4 - 2/3 = 9/12 - 8/12 = 1/12

Л) = -5/8 + 6/8 = 1/8

М) = -12/15 + 10/15 = -2/15

Н) = -3. 3/4 + 2. 2/4 = -1. 1/4

О) = -6/16 + 5. 1/16 =

-6/16 + 4. 17/16 = 4. 11/16

П) = 2. 8/14 - 3. 5/14 =

2. 8/14 - 2. 19/14 = -11/14

Р) = 5. 4/9 - 5. 4/9 = 0

Answer 2

и)$\frac{5}{9}+(-\frac{8}{9})=\frac{5}{9}- \frac{8}{9} =\frac{5-8}{9}=\frac{-3}{9} =-\frac{3}{9} =-\frac{1}{3}$

к)$\frac{3}{4}+(-\frac{2}{3} )=\frac{3}{4}-\frac{2}{3} =\frac{9}{12}-\frac{8}{12} =\frac{9-8}{12} =\frac{1}{12}$

л)$-\frac{5}{8} +\frac{3}{4} =-\frac{5}{8}+\frac{6}{8} =\frac{-5+6}{8}=\frac{1}{8}$

м)$-\frac{4}{5} +\frac{2}{3} =-\frac{12}{15} +\frac{10}{15} =\frac{-12+10}{15} =\frac{-2}{15} =-\frac{2}{15}$

н)$-3\frac{3}{4}+2\frac{1}{2}=-\frac{15}{4} +\frac{5}{2}=-\frac{15}{4}+\frac{10}{4}=\frac{-15+10}{4}=\frac{-5}{4}=-\frac{5}{4}=-1\frac{1}{4}$

о)$-\frac{3}{8} +5\frac{1}{16} =-\frac{6}{16}+\frac{81}{16}=\frac{-6+81}{16}=\frac{75}{16}=4\frac{11}{16}$

п)$2\frac{4}{7} +(-3\frac{5}{14} )=\frac{18}{7} -\frac{47}{14} =\frac{36}{14} -\frac{47}{14} =\frac{36-47}{14}=\frac{-11}{14} =-\frac{11}{14}$

р)$5\frac{4}{9} +(-5\frac{4}{9} )=5\frac{4}{9} -5\frac{4}{9} =0$
