Solve: 310 - 110.352 Using Vertical Subtraction Method

Question

Circle the correct answer to the following exercise:

310-110.352

Video Solution

Step-by-Step Solution

To avoid confusion in solving the exercise, we'll first add three zeros to the number 310 as follows:

310.000110.352 310.000\\-110.352\\

Now let's solve the exercise in order:

Let's subtract the thousands after the decimal point:

02= 0-2=

Since we cannot subtract, we'll 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 0, 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:

102=8 10-2=8

Let's subtract the hundreds after the decimal point:

95=4 9-5=4

Let's subtract the tenths after the decimal point:

93=6 9-3=6

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

90=9 9-0=9

01= 0-1=

Since we cannot subtract, we'll borrow ten from the ones digit of the whole number and we get:

101=9 10-1=9

Remember that we borrowed ten from the ones digit, so we get:

311=1 3-1-1=1

And we get:

310.000110.352199.648 310.000\\-110.352\\199.648

Answer

199.648
