I am greater than 10. I am less than 20. One of my factors is double the other. what number am i?
18
Thanks....
You're welcome.
To find the number that satisfies these conditions, we can break down the problem into steps:
1. Start by listing the numbers from 10 to 20 (inclusive).
- This gives us the numbers: 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, and 20.
2. Check each number to see if it matches the condition "one factor is double the other."
- For each number, find its factors by dividing it by smaller numbers (starting from 1) until you reach a number that is greater than half of the original number.
- For example, let's take the number 12:
- The factors of 12 are: 1, 2, 3, 4, 6, and 12.
- One of the factors must be double the other. By checking, we can see that 4 is double 2.
- So, 12 satisfies the condition.
3. Check if the remaining numbers also satisfy the condition.
- By following step 2, continue checking each number until we find the one that satisfies the condition.
In this case, the number you are looking for is 12, since it is greater than 10, less than 20, and has one factor (4) that is double the other factor (2).
