the number is less than 20 it is an odd 1 digit number, is not the number of sides of a triangle it can be divided by 3
Odd 1-digit numbers:
1, 3, 5, 7, 9
Which one of those numbers fits the problem?
i belive it is 1
could be 5 or 7
You are both wrong.
Read the problem carefully.
Its 9
Right, Gio.
it is definitely 9
9
To find the number that satisfies all the given conditions, we can follow a step-by-step approach:
1. Start with the range of numbers less than 20.
2. Narrow down the selection to odd 1-digit numbers. These are the numbers 1, 3, 5, 7, and 9.
3. Eliminate any number that is the number of sides of a triangle. The numbers 3, 5, and 7 are triangle numbers (since a triangle can have 3, 4, or 5 sides).
4. Check each remaining number to see if it is divisible by 3. Of the remaining numbers, only the number 9 can be divided evenly by 3.
Therefore, the number that satisfies all the given conditions is 9.
