Solution Steps

00:00 Solve

00:03 Let's start subtracting from right to left

00:06 The digit is too small for subtraction, so we'll borrow from the next

00:09 The next digit will decrease by 1, and our digit will increase by 10

00:13 Now let's subtract from the larger number

00:22 Calculate and write accordingly

00:28 Again the digit is too small for subtraction, so we'll borrow from the next

00:33 We'll use the same method

00:44 Calculate and write accordingly

00:51 Continue subtracting, calculating, and writing accordingly

01:09 And this is the solution to the question

Step-by-Step Solution

To solve this problem of subtracting $0.66$ from $16.44$ , we need to perform the following steps:

$\begin{aligned} 16.44 \\ \underline{-~~ 0.66}\\ \end{aligned}$

Step 2: Subtract the hundredths place:
4 minus 6 cannot be done without borrowing. Borrow 1 from the tenths place, so it becomes 3, and the hundredths becomes 14.
$14 - 6 = 8$ .
Step 3: Subtract the tenths place (after borrowing):
3 minus 6 again requires borrowing. Borrow 1 from the units place, leaving it as 5. The tenths place becomes 13.
$13 - 6 = 7$ .
Step 4: Subtract the units place:
5 minus 0 gives $5$ .
Step 5: Subtract the tens place:
1 minus 0 gives $1$ .
This gives us a final result of $15.78$ .
Therefore, the solution to the problem is $\text{15.78}$ .
