Nearest 10 or nearest 100 are the basic questions of rounding off.
This is one of the major chapters in basic mathematics.
For example:
If we want to round off a digit to its nearest 10, we look at the following steps:
1- What is the question?
a- 09 : Look at the digit on the right side, if this digit is greater than the number 5, you will increase the number.
like this, : 09(9+1) = 10; as 9 is the right digit.
see!
T(tens) U(units)
0 9
2- Now look at the questions, you asked me to answer?
a- 48 : look at the digit on the right, is it more than 5?
the answer is yes!
so now lets increase it.
48(8+1) = 9
this will become, 50?
HOW?
Because, your right digit is more than 5 after 1 being added to it, so your total will automatically move forward towards the nearest 10.
3- Lets look at one more question,
Remember, we are supposed to round off to the nearest 10.
So we must see that the total must have a 0 at the end, after getting rounded off to the nearest 10, this is a tip
4- now lets do the other questions:-
a- 48 becomes 50
b- 62 becomes 60. WHY?, because 2 is less than 5 so we will go backwards.
c- 81 becomes 80. WHY?, because 1 is less than 5 so again we will go backwards.
d- 94 becomes 90. WHY?, because 4 is less than 5, so similarly, it will become 90.
e- 27 becomes 30. WHY did we increase? because 7 is larger than 5, so we will increase, add, move in forward direction. Therefore, making it 30.
