As we know, subtraction in decimal works exactly like normal subtraction, we just have to maintain the place of decimal.

So

(a) Rs \small 18.25  from Rs \small 20.75

     20.75

 -18.25


      2.50 Rs


(b)  \small 202.54 m from 250 m\

    250.00

-202.54


     47.46 m 


(c)Rs \small 5.36  from Rs \small 8.40

    8.40

-5.36


   3.04 Rs


(d )  \small 2.051 km from \small 5.206 km

    5.206

-2.051


    3.155 km 


(e)  \small 0.314 kg from \small 2.107 kg 

        2.107

     -0.314


        1.793 kg
