To determine the number in the fourth row on the hundred chart, where the ones digit is twice the tens digit, we can follow these steps:
1. Identify the corresponding row and column:
- The fourth row means we need to find the number at the 4th row of the chart.
- Since each row contains ten numbers, the fourth row has the numbers from 31 to 40.
2. Analyze the condition:
- The ones digit is twice the tens digit.
- Therefore, we need to find a number where the ones digit is twice the tens digit.
3. Test each number in the fourth row:
- Start with the first number in the fourth row, which is 31.
- Check if the ones digit is twice the tens digit: 1 * 2 = 2. This is not true for 31.
- Move to the next number, 32, and check again. 2 * 2 = 4. This is not true for 32 either.
- Continue this process for each number in the fourth row.
4. Find the number that satisfies the condition:
- After testing the numbers, we find that the number which satisfies the condition is 34.
- In this number, the ones digit (4) is indeed twice the tens digit (2).
Therefore, the number you are referring to is 34.
