Rules for Subtracting Decimals

  • Convert the decimal fractions to decimals.
  • Use column subtraction so that the larger number is above the smaller number. Make sure the decimal places of two numbers are on the same line.
  • Always subtract the digits from Right to left.
  • If the digit is smaller to subtract the other digit in the lower row then borrow from the left number.
  • Place the decimal point after subtraction which is as many decimal places similar to the subtracting numbers.
  • Check whether the subtraction is between the smaller decimal and larger decimal or between the larger decimal and the smaller decimal.
  • If the subtraction is between the smaller decimal and the larger decimal then include a negative sign in the answer.
