Round off to nearest 10 is discussed here.



A large number may be rounded off to the nearest 10.

1. 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.

2. 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.



Round off to nearest 10.

For Example:

(i) 4 → 0

Since 4 < 5

(ii) 07 → 10

Since units digit is 7

(iii) 62 → 60

Since 2 < 0

(iv) 2983 → 2980

Since 3 < 5

(v) 597324 → 597320

Since 4 < 5

(vi) 5057 → 5060

Since units digit is 7

(vii) 6275985 → 6275990

Since units digit is 5
