Rounding off to nearest ten (10)
Suppose we are given the number
432
Rounding off to nearest tens means
We write numbers as 430 or 440
Since 430 is near to 432.
In general
Numbers 431, 432, 433, 434 will be rounded off to 430.
Numbers 436, 437, 438, 439 will be rounded off to 440
Number 435, the middle most number will always be larger, i.e 440
