Solve the following exercise and circle the appropriate answer:
Let's solve the exercise in order:
Let's subtract the hundreds after the decimal point
Let's subtract the tenths after the decimal point:
Since we cannot subtract, we'll borrow ten from the tens digit of the whole number and get:
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:
And we get:
We can ignore the 0 before the 2, so we got the number: 2.94
2.94
Choose the correct writing form:
Lining up decimal points ensures you're subtracting like place values - tenths from tenths, hundredths from hundredths. Without proper alignment, you'll get completely wrong answers!
Borrowing means taking 10 from the next higher place value when you can't subtract. For example, when 2 - 3 is impossible, borrow 10 from the tens place to make it 12 - 3 = 9.
You need to borrow whenever the top digit is smaller than the bottom digit in any column. Like 2 < 3 in the tenths place of this problem!
The digit you borrow from gets reduced by 1. In our problem, the 6 in the tens place became 5 after we borrowed 10 for the tenths column.
Yes! Add your answer to the number you subtracted. If you get the original number, you're correct: ✓
The leading zero shows the borrowing process clearly, but we don't need it in our final answer. Both 02.94 and 2.94 represent the same number!
