    The distance between -1.3 and \(3\dfrac{1}{8}\) is : \(3\dfrac{1}{8}+1.3=4.425\)

    The distance between -1.3 and the point is : \(4.425\times\dfrac{2}{3}=2.95\)

    The answer is : \(-1.3+2.95=1.65\)

    The answer: \(\dfrac{2}{3}\left(3\dfrac{1}{8}-\left(-1,3\right)\right)=\dfrac{59}{20}=2,95\)
