clue#1 You will use exactly eleven base-ten blocks. Clue#2 The number is less than 300. Clue#3 The digit in the tens place is one less than the digit in the ones place. Who am I? Mom of second grader, can't help her with this!! Can you explain how to figure the answer?
To solve this problem, we need to find a number that meets all the given clues. Let's break down each clue and figure out how to use it to find the answer.
Clue#1: You will use exactly eleven base-ten blocks.
This clue tells us that the number we're looking for can be represented using exactly eleven base-ten blocks. In the base-ten system, each block represents a power of 10 (ones, tens, hundreds, etc.). So, we need to find a number that can be represented using eleven blocks.
Clue#2: The number is less than 300.
This clue tells us that the number we're looking for is less than 300. This narrows down our search range.
Clue#3: The digit in the tens place is one less than the digit in the ones place.
This clue gives us a relationship between the tens and ones place digits of the number. The digit in the tens place is one less than the digit in the ones place. For example, if the digit in the ones place is 5, the digit in the tens place must be 4.
Now that we understand each clue, we can use them to systematically find the answer. Here's how we can do it:
1. Start with a number less than 300.
2. Check if the number can be represented using exactly eleven base-ten blocks.
3. Check if the digit in the tens place is one less than the digit in the ones place.
4. If the number satisfies all the clues, it could be the answer.
5. If not, continue with the next number until you find the one that meets all the clues.
Let's go through an example to find the answer:
Start with the number 200:
- It can be represented using three blocks (2 hundreds and 0 tens).
- The digit in the tens place is 0, which is not one less than the digit in the ones place (0).
- So, 200 is not the answer.
Continue with the next number, 201:
- It can be represented using three blocks (2 hundreds and 1 ten).
- The digit in the tens place is 1, which is indeed one less than the digit in the ones place (0).
- Hooray! 201 satisfies all the clues, so it could be the answer!
Therefore, the answer to the riddle "Who am I?" could be the number 201.
