Decimals Examples

Let us consider a decimal number 0.5694 to see the different place values of each digit –

  • The value of the digit at the first place after the decimal point is tenths place value. Tenths can be calculated as 1 unit divided in 10 equal parts i.e 0.1. Therefore, considering this there are 5 tenths in the number 0.5694.
  • The value of the digit at the second place after the decimal point is hundredths place value. The number in that place tells you how many hundredths are there. Hundredths can be calculated as 1 unit divided in100 equal parts i.e 0.01. Therefore, considering this there are 6 hundredths in the number 0.5694
  • The value of the digit at the third place after the decimal point is thousandths place value. The number in that place tells you how many thousandths are present. Thousandths can be calculated as 1 unit divided in1000 equal parts i.e 0.001. Therefore, considering this there are 9 thousandths in the number 0.5694
  • Ten-thousandths
  • The value of the digit at the fourth place after the decimal point is ten-thousandths place value. The number in that place tells you how many ten-thousandths are present. Ten-thousandths can be calculated as 1 unit divided into 10000 equal parts i.e 0.0001. Therefore, considering this there are 4 thousandths in the number 0.5694
