Question

вычислите
-16 целых 8/25-7,3
-5,8-17 целых 3/4

Answer 1

$-16 frac{8}{25} -7.3= -frac{16*25+8}{25} - frac{73}{10} =- frac{408}{25} - frac{73}{10} = frac{-408*2-73*5}{50} =- frac{1181}{50} =-$$23.62$

$-5.8-17 frac{3}{4} = -frac{58}{10}- frac{17*4+3}{4} =- frac{58}{10} - frac{71}{4} = frac{-58*2-71*5}{20}=- frac{471}{20}=-23.5$$5$
