Solve the following exercise in the correct order:
Subtract the hundreds after the decimal point:
Given that we cannot subtract, we will instead borrow ten from the tenths digit after the decimal point as shown below:
Let's subtract the tenths after the decimal point, remembering that we borrowed ten, therefore:
Since we cannot subtract, we will instead borrow ten from the tens digit of the whole number to obtain the following:
Finally, let's subtract the whole numbers before the decimal point accordingly.
Let's remember that we borrowed ten from the tens digit, therefore:
We obtain the following result:
Ignoring the zero before the 3 we obtain the number: 3.89
3.89
\( \text{0.6+0}.5= \)
Just like with whole numbers, you borrow when the top digit is smaller than the bottom digit. For example, you can't do 8-9, so you borrow 10 from the next place value to make it 18-9.
When you borrow from the tenths place, you're taking 1 tenth (which equals 10 hundredths) and adding it to the hundredths place. So 2 tenths becomes 1 tenth, and 8 hundredths becomes 18 hundredths.
Always borrow from the place value to the left. If you need help in hundredths, borrow from tenths. If you need help in tenths, borrow from ones, and so on.
This is a very common mistake! When you borrow 10, you must subtract 1 from the place you borrowed from. If you forget this step, your final answer will be wrong.
Yes! Add your answer to the number you subtracted. For example: . If you get the original number, you're correct!
During calculation, we sometimes write leading zeros to keep track of place values. The final answer is 3.89 because we don't need the leading zero in our final result.
