$\dfrac{(\dfrac{11^2}{200}+0,415):\dfrac{1}{1000}}{\dfrac{1}{12}-37,25+3\dfrac{1}{6}}$
Đáp án:
`-30`
Giải thích các bước giải:
$\dfrac{(\dfrac{11^2}{200}+0,415):\dfrac{1}{1000}}{\dfrac{1}{12}-37,25+3\dfrac{1}{6}}$
$= \dfrac{ ( \dfrac{121}{200} + \dfrac{83}{200} ) . 1000} { \dfrac{1}{12} – \dfrac{149}{4} + \dfrac{19}{6}}$
$=\dfrac{ \dfrac{51}{50} . 1000}{ \dfrac{1-149.3+19.2}{12} }= \dfrac{1020}{ \dfrac{-408}{12}}$
$=\dfrac{1020}{-34}=-30$
Đáp án:
Giải thích các bước giải:
`((11^2)/(200) + 0,415) : 1/1000) : (1/12 – 37,25 + 3 1/6)`
`= ((0,605 + 0,415) × 1000)/(1/12 – 37,25 + (17)/6`
`= (1,02 × 1000)/(-223/6 + 19/6)`
`= 1020/-34`
`= – 30`
