Reading and Writing Decimals

Let’s go over how to write and read decimals.

Decimals are used to write fractional amounts. A decimal number contains a decimal point which allows you to write large and small numbers. Numbers to the left of the point get ten times larger and numbers to the right of the point get ten times smaller.

 

Numbers to the left of the decimal start at ones and increase by ten times.

Numbers to the right of the decimal point start at tenths and get ten times smaller.

Let’s review a couple of items that will help when reading and writing a decimal.

1.Decimals are to the right of the decimal point.

2.Instead of increasing by ten times the number like numbers to the left of the decimal point, numbers to the right of the decimal point are ten times smaller.

3.There is no one’s place with decimals.

4.A decimal number has three parts, a whole number, a decimal number, and a fractional part.

5.A decimal is read from left to right.

Let’s go over the steps for reading a decimal.

1.Read the number before the decimal point.

2.At the decimal point say “and”

3.Read the number after the decimal point,

4.In order to finish, say the name of the place of the final digit and add “ths”.

0.5  Is read zero and 5 tenths

0.0363 is read zero and three hundred and sixty-three ten thousandths

72.4  is read seventy-two and 4 tenths
