- Decimals:When we use dots to write some numbers then that dot is the decimal point. This is used to show the part of a whole number.
- Tenths: As we know that 1 cm = 10 mm, so if we have to find the opposite then 1mm = 1/10 cm or one-tenth cm or 0.1 cm.
Hence, the first number after the decimal represents the tenth part of the whole.
- Hundredths: As we know that 1 m = 100 cm, so if we have to find the opposite then 1 cm = 1/100 m or one-hundredth m or 0.01 m. Hence, the second numbers after the decimal represent the hundredth part of the whole.
- Place Value Chart:This is the place value chart which tells the place value of each digit in the decimal number. It makes it easy to write numbers in decimal form.
