To avoid confusion when solving the exercise, we will first add the digit 0 to the number 112.3 as follows:
First we'll combine the hundredths after the decimal point:
Next we'll combine the tenths after the decimal point:
Finally, we'll combine the whole numbers before the decimal point accordingly:
This gives us:
223.55
Choose the correct writing form:
Adding zero to make 112.30 helps you see the place values clearly! Both numbers now have the same number of decimal places, making column addition much easier and preventing mistakes.
You'll get the wrong answer every time! For example, if you add 111.25 + 112.3 without proper alignment, you might get 223.28 instead of the correct 223.55.
The decimal point in your answer goes directly below the decimal points in the problem. It stays in the same column throughout the addition process.
It's much harder and error-prone! Standard right-to-left addition (starting from hundredths, then tenths, then ones) follows the same pattern you learned with whole numbers.
Add zeros as placeholders to make them match! For example, 112.3 becomes 112.30, and 5.7 becomes 5.70. This creates equal decimal places for easier alignment.
Yes! If any column adds up to 10 or more, carry the extra to the next column just like with whole numbers. The decimal point doesn't change this rule.
