Question

вычислите: 30 13/30 + 0,2 - (3 19/33 + 2/3) : (17 5/6 - 17 15/22) + 1/3 * 9,5

Answer 1

1) 3 19/33 + 2/3 = 3 19/33 + 22/33 = 3 41/33 = 4 8/33
2) 17 5/6 - 17 15/22 = 17 55/66 - 17 45/66 = 10/66
3) 1/3 • 9,5 = 1/3 • 95/10 = 95/30 = 3 1/6
4) 4 8/33 : 10/66 = 140/33 : 10/66 = 28
5) 30 13/30 + 0,2 - 28 + 3 1/6 = 30 13/30 + 3 5/30 - 27,8 = 33 18/30 - 27,8 = 33,6 - 27,8 = 5,8
Ответ 5,8

Answer 2

$30frac{13}{30}+0.2- (3frac{19}{33}+ frac{2}{3}): (17frac{5}{6}- 17frac{15}{22})+ frac{1}{3}*9.5=$
$1) 3frac{19}{33}+ frac{2}{3}= frac{118}{33}+ frac{2}{3}= frac{118}{33}+ frac{22}{33}= frac{140}{33}$
$2) 17frac{5}{6}- 17frac{15}{22}= frac{107}{6}- frac{389}{22}= frac{2354}{132}- frac{2334}{132}= frac{20}{132}= frac{5}{33}$
$3) frac{140}{33}: frac{33}{5}=28$
$4) frac{1}{3}*9.5= frac{1}{3}* frac{95}{10}= frac{95}{30}= frac{19}{6}$
$5) 30frac{13}{30}+0.2=30 frac{13}{30}+ frac{2}{10}= frac{913}{30}+ frac{2}{10}= frac{913}{30}+ frac{6}{30}= frac{919}{30}$
$6) frac{919}{30}-28= frac{919}{30}- frac{840}{30}= frac{79}{30}$
$7) frac{79}{30}+ frac{19}{6}= frac{79}{30}+ frac{95}{30}= frac{174}{30}=5.8$
