Easy Method to Calculate the Difference Between 11.97 and 7.23
To find the difference between two decimals, such as 11.97 and 7.23, one can follow these straightforward steps:
- Align the Numbers by Decimal Point: Ensure that the decimals are aligned properly. This typically involves writing one number above the other with the decimal points lined up.
- Subtract from Right to Left: Begin subtraction from the farthest right digit and move left. Borrow from the next left digit if necessary.
- Solve Step-by-Step:
- Subtract the hundredths place: 7−3=47 – 3 = 47−3=4
- Subtract the tenths place: 9−2=79 – 2 = 79−2=7
- Subtract the units place: 11−7=411 – 7 = 411−7=4
Thus, the difference between 11.97 and 7.23 is 4.74.
Significance of Decimal Subtraction
Decimal subtraction is more than just a basic arithmetic operation; it is integral to maintaining accuracy in measurements, financial calculations, and data analysis. Without proper understanding and execution of decimal operations, errors can cascade, leading to significant discrepancies in results.
