Question

(\(2\dfrac{1}{3}\) + \(3\dfrac{1}{2}\)) : (\(-4\dfrac{1}{6}\)+\(3\dfrac{1}{7}\)) + \(7\dfrac{1}{2}\)

Answer 1

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

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

= \(-\dfrac{245}{43}+\dfrac{15}{2}\) = \(\dfrac{155}{86}\)

Answer 2

=(7/3+7/2):(-23/6+22/7)+15/2

=35/6:(-29/42)+15/2

=-245/43+15/2

=155/86
