Round off to Nearest 10
Round off to nearest 10 is discussed here. Rounding can be done for every place-value of number. To round off a number to the nearest tens, we round off to the nearest multiple of ten.
A large number may be rounded off to the nearest 10.
Rules for Rounding off to the Nearest 10:
Rule I. While rounding off to the nearest ten if the digit in the units place is between 0 – 4 i.e., < 5 then the unit digit is replaced by 0.
Rule II. If the digit in the units place is 5 to 9 i.e., > or 5 but < 10, then the units place is replaced by ‘0’ and the tens place increased by 1.
Examples on rounding off to the nearest ten (10):
1. Aaron has 63 marbles rounded 63 to the nearest tens.
63 lies between 60 and 70 (multiples of 10)
63 is nearer to 60 than 70
So, we can say Aaron has about 60 marbles.
Similarly let us round the following numbers to the nearest ten.
(i) 43 → 40
We see the digit in the ones place is 3, now round to the nearest multiple of 10 which is smaller than the number. Hence, 43 is nearer to 40 than 50.
(ii) 158 → 160
We see the digit in the ones place is 8, now round to the nearest multiple of 10 which is greater than the number. Hence, 158 is nearer to 160 than 150.
(iii) 3501 → 3500
We see the digit in the ones place is 1, now round to the nearest multiple of 10 which is smaller than the number. Hence, 3501 is nearer to 3500 than 3510.
(iv) 1023 → 1020
We see the digit in the ones place is 3, now round to the nearest multiple of 10 which is smaller than the number. Hence, 1020 is nearer to 1020 than 1030.
(v) 6275985 → 6275990
We see the digit in the ones place is 5, now round to the nearest multiple of 10 which is greater than the number. Hence, 6275985 is nearer to 6275990 than 6275980.
2. Round off 14,57,894 to the nearest 10.
Solution:
We choose the two multiple of 10 just greater than and just less than 14,57,894 on the number line.
We observe that 14,57,894 is closer to 14,57,890. So, it is rounded down to 14,57,890.
Frequently asked questions on Round off to Nearest 10
1. How do you round to the nearest 10?
Step I: Replace ones digit by 0.
Step II: If ones digit is 5 or more than 5, then increase the tens digit by 1, otherwise do not change the tens digit.
Step III: Leave rest of the digits unchanged.
2. Round off to the nearest ten: 947
Solution:
3. Round off to the nearest ten: 947; (ii) 9853.
Solution:

Addition of Integers | Adding Integers on a Number Line | Examples
We will learn addition of integers using number line. We know that counting forward means addition. When we add positive integers, we move to the right on the number line. For example to add +2 and +4 we move 4 steps to the right of +2. Thus, +2 +4 = +6.

Properties of Division | Division of Property Overview|Math Properties
The properties of division are discussed here: 1. If we divide a number by 1 the quotient is the number itself. In other words, when any number is divided by 1, we always get the number itself as the quotient. For example: (i) 7542 ÷ 1 = 7542 (ii) 372 ÷ 1 = 372
Multiplication by Ten, Hundred and Thousand |Multiply by 10, 100 &1000
