Answer:
The rounded to the nearest ten is 690.
Explanation:
Consider the provided number 686.924
We need to round it to the nearest ten.
The rule of rounding a number is:
If 0, 1, 2, 3, or 4 follow the number, then no need to change the rounding digit.
If 5, 6, 7, 8, or 9 follow the number, then rounding digit rounds up by one number.
To round nearest tens look at the number at ones place.
Here, the number at the ones place is 6, so to round up the number increase the digit of tens place by 1.
The digit at the tens place is 8 so increase it by 9.
Thus, the number can be rounded to the nearest tens is shown as:
690
Thus the rounded to the nearest ten is 690.
