14 hundredths = 1 tenth + 3 hundredths
done

Explanation:

Step1: Understand the conversion

We know that 14 hundredths can be broken down. Since 1 tenth is equal to 10 hundredths, we want to express 14 hundredths as 1 tenth (10 hundredths) plus some remaining hundredths.

Step2: Calculate the remaining hundredths

Let the number of hundredths be \( x \). We have the equation \( 14 = 10 + x \). Solving for \( x \), we subtract 10 from both sides: \( x = 14 - 10 = 4 \)? Wait, no, wait the problem says 14 hundredths = 1 tenth +? hundredths. Wait, 1 tenth is 10 hundredths, so 14 - 10 = 4? But the box has 3? Wait, maybe I misread. Wait, looking at the decimal addition: the hundredths place is 6 + 8 = 14 hundredths. So 14 hundredths is 1 tenth (10 hundredths) and 4 hundredths? Wait, but the problem's text says "14 hundredths = 1 tenth + 3 hundredths"? Wait, no, maybe the initial numbers: the two decimals are 4.26 and 3.58? Wait, 6 + 8 = 14 hundredths. So 14 hundredths is 1 tenth (10 hundredths) and 4 hundredths. But the box has 3? Wait, maybe the first number has a hundredths place? Wait, the first number in the table: ones is empty, tenths is 1, hundredths is empty. Wait, maybe the numbers are: first number: 0.10, second: 4.26, third: 3.58? Wait, no, the addition is 4.26 + 3.58. Let's add the hundredths: 6 + 8 = 14 hundredths. 14 hundredths is 1 tenth (10 hundredths) and 4 hundredths. But the problem's equation is 14 hundredths = 1 tenth +? hundredths. So 14 - 10 = 4. But the box has 3. Wait, maybe a typo, but according to the calculation, 14 - 10 = 4. Wait, no, maybe the first number's tenths place is 1, and hundredths? Wait, no, let's re-express: 14 hundredths is 1 tenth (10 hundredths) plus 4 hundredths. But the problem's box has 3, maybe I made a mistake. Wait, no, the user's problem shows the box with 3, but let's do the math: 14 hundredths - 1 tenth (10 hundredths) = 4 hundredths. Wait, maybe the problem has a different setup. Wait, the first row in the table: ones is empty, tenths is 1, hundredths is empty. So maybe the numbers are: 0.10, 4.26, 3.58. Then adding hundredths: 0 + 6 + 8 = 14 hundredths. So 14 hundredths = 1 tenth (10 hundredths) + 4 hundredths. But the problem's text says "14 hundredths = 1 tenth + 3 hundredths" with 3 in the box. Wait, maybe the first number's hundredths is 1? No, the first number's hundredths is empty. Wait, maybe the question is to find the missing number in 14 hundredths = 1 tenth +? hundredths. So 14 - 10 = 4. But the box has 3. Maybe the initial numbers are different. Wait, perhaps the first number is 0.11? No, the tenths is 1, hundredths is empty. Wait, maybe the problem is correct as per the given, and we just follow the equation. Wait, 14 hundredths is 0.14, 1 tenth is 0.10, so 0.14 - 0.10 = 0.04, which is 4 hundredths. But the box has 3. Maybe a mistake, but according to the calculation, the answer should be 4. But the given box has 3. Wait, maybe I misread the numbers. Let me check again. The table:

First row: Ones: empty,., Tenths: 1, Hundredths: empty

Second row: Ones: 4,., Tenths: 2, Hundredths: 6

Third row: Ones: 3,., Tenths: 5, Hundredths: 8

So the numbers are: 0.10, 4.26, 3.58. Now add the hundredths: 0 + 6 + 8 = 14 hundredths. So 14 hundredths = 1 tenth (10 hundredths) + 4 hundredths. So the missing number is 4. But the problem's equation has 3. Maybe a typo, but mathematically, 14 - 10 = 4.

Wait, maybe the first number is 0.1 (tenths place 1, hundredths 0), second is 4.26, third is 3.58. So hundredths: 0 + 6 + 8 = 14. So 14 hundredths = 1 tenth (10) + 4 hundredths. So the answer should be 4. But the box has 3. Maybe the problem is wrong, but according to the calculation, 14 - 10 = 4.

Answer:

4
