Solve the following exercise:
To avoid confusion in solving the exercise, we will first add the digit 0 to the number 6.55 as follows:
Now let's solve the exercise in order:
Let's add the thousandths after the decimal point:
Let's add the hundredths after the decimal point:
Let's add the tenths after the decimal point:
Finally, let's add the whole numbers before the decimal point:
And we obtain the following:
9.962
Choose the correct writing form:
Adding zero to make 6.550 doesn't change the value, but it helps you see all place values clearly. Now you can easily add thousandths (0+2), hundredths (5+1), and tenths (5+4)!
Always add trailing zeros to make both numbers have the same number of decimal places. For example, 6.55 becomes 6.550 to match 3.412's three decimal places.
The decimal point in your answer goes in the same column as the decimal points you lined up in the problem. If you align them properly, the answer's decimal point falls right into place!
Yes! Carrying works exactly the same as with whole numbers. If 5+4=9 in the tenths place, write 9. If you get 8+7=15, write 5 and carry the 1 to the next column.
Absolutely! Try adding in reverse order: . You can also use estimation: 6.55 is about 7, and 3.412 is about 3, so 7+3=10 is close to 9.962!
