Question

помогите 293 дам 50 БАЛЛОВ

Answer 1

Ответ: 1) 12 1\3

2) 32

Пошаговое объяснение:

1) $1\frac{15}{23} = \frac{38}{23}\\ 3\frac{17}{22}=\frac{83}{22}\\  2\frac{7}{15}=\frac{37}{15} \\ 1\frac{8}{5}=\frac{13}{15} \[tex]\frac{38}{23}+\frac{77}{23}=\frac{115}{23}=5\\\frac{83}{22}+\frac{5}{22}=\frac{88}{22}=4\\\frac{37}{15}+\frac{13}{15}=\frac{50}{15}=\frac{10}{3}    \\5 + 4 +\frac{10}{3}= \frac{15+12+10}{3}=\frac{37}{3}=12\frac{1}{3}$\ 3\frac{8}{23}=\frac{77}{23}[/tex]

2) $9\frac{5}{16}=\frac{149}{16}\\  1\frac{3}{5}=\frac{8}{5}\\  2\frac{1}{7}=\frac{15}{7} \\ 11\frac{11}{16}=\frac{187}{16} \\ 1\frac{2}{5} =\frac{7}{5} \\5\frac{6}{7}=\frac{41}{7} \\\frac{149}{16}+\frac{187}{16}=\frac{336}{16}=21\\\frac{8}{5}+\frac{7}{5}=\frac{15}{5}=3\\\frac{15}{7}+\frac{41}{7}=\frac{56}{7}=8\\           21+3+8=32$
