Comparing and Ordering Decimals

A decimal is a number that has a whole part and a fractional part, separated by a decimal point. For example, 3.14 is a decimal.

To compare decimals, look at the digits from left to right. The first digit that differs determines which decimal is larger or smaller.

Ordering decimals means arranging them from the smallest to the largest or vice versa.

0.5 is greater than 0.05.

The value of the digit 3 in 4.36 is 3 tenths, or 0.3.

14.73 rounded to the nearest whole number is 15.

The smallest decimal number is 0.

0.25 is larger than 0.2.

0.7 can be written as 7/10.

To add decimals, align the decimal points and add as you would whole numbers.
