Question

Tính :

$M=\left(2\dfrac{1}{3}+3,5\right):\left(-4\dfrac{1}{6}+3\dfrac{1}{7}\right)+7,5$

Trần Ngọc Bích Vân · Accepted Answer

$M=\left(2\dfrac{1}{3}+3,5\right):\left(-4\dfrac{1}{6}+3\dfrac{1}{7}\right)+7,5$

$M=\left(\dfrac{7}{3}+\dfrac{7}{2}\right):\left(-\dfrac{25}{6}+\dfrac{22}{7}\right)+\dfrac{15}{2}$

$M=\dfrac{35}{6}:\left(-\dfrac{43}{42}\right)+\dfrac{15}{2}$

$M=\left(-\dfrac{245}{43}\right)+\dfrac{15}{2}$

$M=\dfrac{155}{86}$Câu trả lời: $M=\left(2\dfrac{1}{3}+3,5\right):\left(-4\dfrac{1}{6}+3\dfrac{1}{7}\right)+7,5$

$M=\left(\dfrac{7}{3}+\dfrac{7}{2}\right):\left(-\dfrac{25}{6}+\dfrac{22}{7}\right)+\dfrac{15}{2}$

$M=\dfrac{35}{6}:\left(-\dfrac{43}{42}\right)+\dfrac{15}{2}$

$M=\left(-\dfrac{245}{43}\right)+\dfrac{15}{2}$

$M=\dfrac{155}{86}$
