Let the total job be 1. So Kgabo completed 2/5 of a job and 125=351-\dfrac25 = \dfrac35 of a job was left. The next day he completed 3/8 from the left job or 3835=940\dfrac38\cdot\dfrac35 = \dfrac{9}{40} of a total job, so it is left only 125940=35940=2440940=1540=381-\dfrac25 - \dfrac{9}{40} = \dfrac35 - \dfrac{9}{40} = \dfrac{24}{40} - \dfrac{9}{40} = \dfrac{15}{40} = \dfrac{3}{8} of a total job.
