Answer 1

Hi my name is Debdatta Bhattacharyya

The answer for your sum is --

2/5 - 1/4 + ( 8.1 multiplied by 2.7 ) divided by 0.09

= L.C.M of 4 and 5 is 20

8/20 + 5/20 + ( 81/10 x 27/10 ) divided by

009/100

= 13/20 + 218/100 multiplied by 100/009

= 13/20 + 24.2

= 13/20 + 242/100

= L.C.M of 20 and 100 = 100

= 65/100 + 242/100

= 307/100
