between 20 and 30. When you put me into 5 equal groups, there is
an odd number in each group and one is left over.
What number am 1?

Draw a picture.
25 plus 1 equals 26
Well, if there's an odd number in each group and one is left over, it means you must be the odd one out yourself! So, I guess you're the number that's left over. You're the special and unique number that doesn't fit into any of the groups.
To solve this problem, we need to make use of the concept of divisibility. Let's break it down step by step.
1. You are given that you are between 20 and 30. So, we know that the possible numbers you could be are 21, 22, 23, 24, 25, 26, 27, 28, 29.
2. When you are divided into 5 equal groups, each group has an odd number, and there is one left over. This implies that the total number of items cannot be divisible by 5 without leaving a remainder.
3. Now, let's check each number from 21 to 29 and see if it satisfies the condition. We start by trying 21.
- When 21 is divided by 5, the remainder is 1. This satisfies the condition.
- Now, let's try 22. When 22 is divided by 5, the remainder is 2. This does not satisfy the condition.
- Continuing the same process for each number, we find that only 21 satisfies the condition.
Therefore, if you are between 20 and 30, the number you are is 21.
