Arrange the following numbers in ascending order :
9873426, 24615019, 990357, 9874012, 24620010

Answer

To arrange the numbers 9873426, 24615019, 990357, 9874012, and 24620010 in ascending order, we will follow these steps:

### Step 1: Count the Digits
First, we count the number of digits in each number:
- 9873426 has 7 digits.
- 24615019 has 8 digits.
- 990357 has 6 digits.
- 9874012 has 7 digits.
- 24620010 has 8 digits.

### Step 2: Identify the Number with the Least Digits
The number with the least digits is 990357 (6 digits). So, this will be the first number in ascending order.

### Step 3: Compare the Remaining Numbers
Now, we have four numbers left: 9873426, 9874012, 24615019, and 24620010. Since 990357 is the smallest, we will look at the next smallest numbers, which are 9873426 and 9874012 (both have 7 digits).

### Step 4: Compare the 7-Digit Numbers
Both 9873426 and 9874012 start with 987. To determine which is smaller, we compare the next digits:
- 9873426 (next digit is 3)
- 9874012 (next digit is 4)

Since 3 is less than 4, 9873426 is smaller than 9874012. So, the next number in ascending order is 9873426, followed by 9874012.

### Step 5: Compare the 8-Digit Numbers
Now we have two 8-digit numbers left: 24615019 and 24620010. Both start with 246, so we compare the next digits:
- 24615019 (next digit is 1)
- 24620010 (next digit is 2)

Since 1 is less than 2, 24615019 is smaller than 24620010. Thus, the next number in ascending order is 24615019, followed by 24620010.

### Final Ascending Order
Putting it all together, the ascending order of the numbers is:
1. 990357
2. 9873426
3. 9874012
4. 24615019
5. 24620010

### Summary of Steps
1. Count the digits in each number.
2. Identify the number with the least digits.
3. Compare the remaining numbers with the same number of digits.
4. Determine the order based on the next digits.
5. Write the final ascending order.
