उत्तर
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

Shuffle, the tokens and make a pile in the middle of the group. Now you are ready to start the game.
The first player takes a token from the pile, colours that part of the picture, and puts the token under the pile. The next player does the same, and so on. The winner is the one who first colours the circle completely.]
