Solve: 15.222 - 11.30 Decimal Subtraction Problem

To avoid confusion in solving the exercise, we will first add the digit 0 to the number 11.30 as follows:

$15.222\\-11.300\\$

Now let's solve the exercise in order:

Let's subtract the thousands after the decimal point:

$2-0=2$

Let's subtract the hundreds after the decimal point:

$2-0=2$

Let's subtract the tenths after the decimal point:

$2-3=$

Since we cannot subtract, we will borrow ten from the tens digit in the whole number before the decimal point and get:

$12-3=9$

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

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

$5-1-1=3$

$1-1=0$

And we get:

$15.222\\-11.300\\03.922$
