17 2/3+4 3/8 19 5/9=

Answer 1

Ответ:

$17\frac{2}{3} +4\frac{3}{8} +19\frac{5}{9} = (17+4+19)+(\frac{48}{72} +\frac{27}{72} +\frac{40}{72}) = 40 + \frac{115}{72} = 41\frac{43}{72} ;\\\\17\frac{2}{3} +4\frac{3}{8} -19\frac{5}{9} = (17+4-19)+(\frac{48}{72} +\frac{27}{72} -\frac{40}{72}) = 2 + \frac{35}{72} = 2\frac{35}{72} .$
