 \frac{1}{5}  +  \frac{2}{5}  \\  r : \frac{3}{5}

b.

(250 \times \frac{1}{5} ) + (250 \times \frac{2}{5} ) \\ ( \frac{250}{1}  \times \frac{1}{5} ) + ( \frac{250}{1}  \times \frac{2}{5} ) \\ ( \frac{250}{5}  ) + ( \frac{500}{5}  ) \\  \frac{750}{5}  \\ r : 150

c.

 \frac{250}{1}  - ( \frac{250}{1}  \times \frac{1}{5} ) - ( \frac{250}{1}  \times \frac{2}{5} ) \\  \frac{250}{1}  - ( \frac{250}{5}   ) - ( \frac{500}{5} )  \\ \frac{250}{1}  - \frac{250}{5}    -  \frac{500}{5}  \\ \frac{1250}{5}  - \frac{250}{5}    -  \frac{500}{5}   \\ \frac{1250}{5}  - \frac{750}{5}    \\  \frac{500}{5}  \\ r : 100
