Here are some tips for Decimal Rounding, which aligns with Florida state standards:

Decimal Rounding

Rounding decimals is the same as rounding whole numbers.

• If the digit to the right is less than 5 (0, 1, 2, 3, 4), round down.
• If the digit to the right is 5 or more (5, 6, 7, 8, 9), round up.

Example 1: Round to the nearest tenth

1.   2.64
Since we are rounding to the nearest tenth, we look at the digit to the right - the hundredths place.
The digit in the hundredths place is 4.
So we round 2.64 down to 2.6.

2.   3.4
Since we are rounding to the nearest tenth, we look at the digit to the right - the hundredths place.
There is no digit in the hundredths place.
3.4 is already rounded to the tenths place.

3.   0.998
Since we are rounding to the nearest tenth, we look at the digit to the right - the hundredths place.
The digit in the hundredths place is 9.
So we round 0.998 up to 1.0.

Example 2: Round to the nearest thousandths

1.   5.839
Since we are rounding to the nearest thousandth, we look at the digit to the right - the ten thousandths place.
There is no digit in the ten thousandths place.
5.839 is already rounded to the thousandths place.

2.   2.19053
Since we are rounding to the nearest thousandth, we look at the digit to the right - the ten thousandths place.
The digit in the ten thousandths place is 5.
So we round 2.19053 up to 2.191.

3.   0.4999
Since we are rounding to the nearest thousandth, we look at the digit to the right - the ten thousandths place.
The digit in the ten thousandths place is 9.
So we round 0.4999 up to 0.500.
