Determine the sum of divisors of the number 30 that are two digits, please help?
To find the sum of divisors of 30 that are two digits, we first need to list all the divisors of 30.
The divisors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30.
Out of these divisors, the two-digit divisors are 10 and 15.
The sum of the two-digit divisors is 10 + 15 = 25.
Therefore, the sum of divisors of the number 30 that are two digits is 25.
To determine the sum of divisors of the number 30 that are two digits, we need to find all the divisors of 30 and then sum up the ones that are two digits.
Step 1: Find the divisors of 30
The divisors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30.
Step 2: Identify the two-digit divisors
Among these divisors, the two-digit divisors are 10 and 30.
Step 3: Sum up the two-digit divisors
Adding 10 and 30 gives a total of 40.
Therefore, the sum of the divisors of the number 30 that are two digits is 40.
To find the sum of divisors of a number, you need to find all the divisors of that number and then calculate their sum.
Let's start by finding the divisors of 30. To do this, we can simply divide 30 by each number starting from 1 up to 30 and check if the remainder is 0.
The divisors of 30 are: 1, 2, 3, 5, 6, 10, 15, and 30.
Next, we need to find the divisors that are two digits. In this case, we are looking for divisors between 10 and 99 (inclusive).
Out of the divisors of 30, only 10 and 15 are two digits.
Finally, we can calculate the sum of these two-digit divisors: 10 + 15 = 25.
Therefore, the sum of divisors of the number 30 that are two digits is 25.
