In the chapter of fractions, students had been introduced to the concept of a number representing a part of a whole. In the chapter of Decimals, students learn that every fraction with denominator 10 can be written in decimal notation and vice-versa. Every decimal can be expressed in the form of a fraction. It was said earlier to understand the number line for it will be used extensively in Decimals. Decimals can be shown on a number line.
Every decimal has a point associated with it on the number line. . When one block is divided into 10 equal parts, it means each part is 1/10 or (one-tenth) of a unit. The very same can be written as 0.1 in decimal notation. The notation has a dot and it represents the decimal point, it comes between the units place and the tenths place. Another example would be- One block divided into 100 equal parts means each part is 1/100 (one-hundredth) of a unit. This expression can be written as 0.01 in decimal notation. Decimals find use in everyday life in representing units of money, length and weight.
