Question

BT2: Tìm x

1) \(x.\left(\dfrac{124124}{125125}-1\right)=\dfrac{2222}{5555}:\left[\left(\dfrac{2010}{2121}-1\right):\left(\dfrac{4040}{4141}-1\right)\right]\)

Answer 1

\(x\left(\dfrac{124124}{125125}-1\right)=\dfrac{2222}{5555}:\left[\left(\dfrac{2010}{2121}-1\right):\left(\dfrac{4040}{4141}-1\right)\right]\)

\(x\left(\dfrac{124}{125}-1\right)=\dfrac{2}{5}:\left(-\dfrac{37}{707}:\dfrac{-1}{41}\right)\)

\(-\dfrac{1}{125}x=\dfrac{2}{5}:\dfrac{1517}{707}\)

\(-\dfrac{1}{125}x=\dfrac{1414}{7585}\)

\(x=\dfrac{1414}{7585}:\dfrac{-1}{125}\\ x=\dfrac{-35350}{1517}\)
