Answer: 1.643
Explanation:
In any number each value is ten times greater than the next value. That is in a number 2.222, the value of 2 in the tenth place is 10 times greater than the value of 2 in the hundreths place, also the value of 2 in the hundreths place is ten times greater than the value of two in the thousandths place. If we apply this rule in the above question then our answer is 1.643.
