Solve Decimal Subtraction: 16.33 - 15.59 Step by Step

Question

Solve the following exercise and circle the appropriate answer:

00:00 Solve

00:03 When we need to subtract a number larger than what we have

00:06 We'll borrow from the next number

00:10 The next digit will decrease by 1, and the previous digit will increase by 10

00:14 Now we'll subtract from the larger number

00:17 Again we'll borrow from the next number

00:20 We'll use the same method and subtract

00:34 We'll reduce the 4

00:38 And this is the solution to the problem

Let's solve the exercise in order:

Let's subtract the hundreds after the decimal point

$3-9=$

Since we cannot subtract, we'll borrow ten from the tenths after the decimal point and get:

$13-9=4$

Let's subtract the tenths after the decimal point, remembering that we borrowed ten, therefore:

$3-1-5=2-5$

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

$12-5=7$

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

Since we borrowed ten from the tens digit of the whole number we get:

$6-1-5=0$

$1-1=0$

And we get:

$16.33\\-15.59\\00.74$

We can ignore the 0 before the 0 and therefore we got the number: 0.74

0.74
