Explicación paso a paso:

$\left(1-\dfrac{1}{2} \right)\left(3-\dfrac{2}{3} \right)+4\times1^2\\\\\left(\dfrac{1\times2-1}{2} \right)\left(\dfrac{3\times3-2}{3} \right)+4\times1\\\\\left(\dfrac{2-1}{2} \right)\left(\dfrac{9-2}{3} \right)+4\\\\\left(\dfrac{1}{2} \right)\left(\dfrac{7}{3} \right)+4\\\\\dfrac{1\times7}{2\times3}+4\\\\\dfrac{7}{6}+4\\\\\dfrac{7+4\times6}{6}\\\\\dfrac{7+24}{6}\\\\\boxed{\dfrac{31}{6}=5.17}$
