aashi40: but your division in incorrect

Anonymous: which division is wrong?The first one or the second one?

Anonymous: if you are talking abt the second one,the answer will be 6.7.

Anonymous: It is because when a decimal has a infinite number,then by seeing the number at the left side of the dot,if the number is less than 5 then the number after the dot will decrease by 1

Anonymous: And if the number before the decimal dot is greater than 5 then the number after the decimal will increase by 1.
