Question

How do you round 750,890,002 to the nearest million.

Answer 1

Hint: Here in this question, we have to round off the number to its nearest million. While rounding off the number, the change of the number depends upon the previous number or the number which is present next to the number which we are rounding off. Hence, we obtain the required result for the question.

Complete step-by-step solution:
 In the number system, the representation of numbers is of two kinds. One is Indian system and the other one is the international system.
The international number system is given or represents as

Million	thousands	ones
HundredMillion	Ten million	million	Hundredthousand	Ten thousand	thousand	hundred	ten	one
HM	TM	M	H Th	T Th	Th	H	T	O

Now consider the given number 750,890 ,002.
When we write the given number to there place value we have

Million	thousands	ones
HundredMillion	Ten million	million	Hundredthousand	Ten thousand	thousand	hundred	ten	one
7	5	0	8	9	0	0	0	2

Now we have rounded the number to its nearest million. If we want to round off the number to its nearest million, then we have to consider the hundred thousand place value. So now consider the hundred thousand place value number. The value is 8.

The round off rule says that look for the next smaller place which is towards the right of the number that is being rounded off to. For example, if you are rounding off a digit from tens place, look for a digit in the ones place. If the digit in the smallest place is less than 5, then the digit will not change. Any number of digits after that number becomes zero and this is known as rounding down. If the digit is greater than or equal to 5, then the digit is added with +1. Any digits after that number become zero and this is known as rounding up. The hundred thousand value is 8. So we add one to the million place value and the rest of values of smaller places will become zero. Therefore the round off number of 750,890,002 is 751,000,000.

Note: The number system has two kinds one is Indian number system and other one is International number system. The rounding off method or the rule will be the same for both systems of numbers. The rule will depend on the smaller place value and we determine or round off the number.
