Answer:
1460
Explanation:
Original number is 1 4 5 6
To round to the nearest ten, look at the digit in the 10's place and the digit immediately to the right of it
The digit in the tens place is 5
If the digit to the immediate right of this digit is 5 or greater, round the digit in the tens place up by one digit and set the immediate right digit to 0
So 5 rounds up to 6
The 6 to the immediate right(units place becomes 0)
1 4 5 6 rounded to nearest ten==> 1 4 6 0
