What is 66 round to the nearest ten and hundred

The number can be rounded to the nearest tens is 70 and nearest hundred is 100.

Step-by-step explanation:

Consider the provided number 66.

According to place value.

Thousands   hundreds   Tens   Ones

   1000             100            10        1

We need to round it to the nearest tens.

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.

The digit is at 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 6 so increase it by 1.

Thus, the number can be rounded to the nearest tens is 70.

Now again consider the provided number 66.

We need to round to the nearest hundred.

The provided number can be written as 066

The digit at the hundred place is 0.

Here, the number at the tens place is 6, so to round up the number increase the digit of hundred place by 1.

The digit at the hundred place is 0 so increase it by 1.

Thus, the number can be rounded to the nearest hundred is 100.
