Solve: 95 Minus 31.213 - Decimal Subtraction Practice

In order to avoid confusion whilst solving the exercise, proceed to add three zeros to the number 95 as follows:

$95.000\\-31.213\\$

Solve the exercise in order:

Subtract the thousands after the decimal point:

$0-3=$

Given that we cannot subtract, we'll instead borrow ten from the tens digit of the whole number before the decimal point, since the other numbers are also zeros.

The tens digit of the whole number before the decimal point will become 4, and the hundreds digit of the whole number before the decimal point will become 10

We'll borrow ten from the hundreds digit before the decimal point and it will change from 10 to 9, and now the tenths digit after the decimal point will become 10

We'll borrow ten from the tenths digit after the decimal point and it will change from 10 to 9, and now the hundredths digit after the decimal point will become 10

We'll borrow ten from the hundredths digit after the decimal point and it will change from 10 to 9, and now the thousandths digit after the decimal point will become 10

Now that we know how to solve the exercise, let's subtract the thousands after the decimal point:

$10-3=7$

Let's subtract the hundreds after the decimal point:

$9-1=8$

Let's subtract the tenths after the decimal point:

$9-2=7$

Finally, let's subtract the whole numbers before the decimal point accordingly.

Remember that we borrowed ten from the tens digit, therefore:

$5-1-1=3$

$9-3=6$

And we should obtain the following:

$95.000\\-31.213\\63.787$
