Question

Evaluate:

`0.6/0.3 + 0.16/0.4`

Answer 1

Given, `0.6/0.3 + 0.16/0.4`

∵ `0.6 = 6/10` and `0.3 = 3/10, 0.16 = 16/100` and `0.4 = 4/10`

∴ `0.6/0.3 + 0.16/0.4 = (6/10)/(3/10) + (16/100)/(4/10)`

= `(6/10 xx 10/3) + (16/100 xx 10/4)`  ...[∵ Division is reverse of the multiplication]

= `60/30 + 160/400`

= `6/3 + 16/40`

= `2/1 + 4/10` ...[∵ LCM of 1 and 10 = 10]

= `(20 + 4)/10`  

= `24/10`

= `12/5`

= 2.4
