Worksheet on Decimal Numbers

Practice different types of math questions given in the worksheet on decimal numbers, these math problems will help the students to review decimals number concepts.

The questions on decimal worksheets below include the decimal number system such as converting fractions to decimals; converting decimals to fractions in its lowest terms; writing the decimal places and their place values; converting the unlike decimals to like decimals; etc., will help your child to get valuable practice to improve in math.

⦿ The fractions with the denominators 10, 100, 1000, etc, are known as decimai fractions or simply decimals.

⦿ A decimal consists of two parts- the whole number part and the decimal part.

⦿ While reading a decimal number, its decimal part is read digit-wise.

⦿ The number of digits contained in the decimal part of a decimal gives the number of its decimal place.

⦿ Decimals having the same number of decimal places are called like decimals.

⦿ Decimals having different number of decimal places are called unlike decimals.

⦿ We can convert decimals into fractions and vice-versa.
