Answer:
- <em>Between which two tens does it fall?</em><em> </em><u>Between 25 and 26 tens</u>
<em><u /></em>
- <em>Between which two hundreds does it fall?</em> <u>Between 2 and 3 hundreds</u>
Explanation:
The place-value chart is:
Hundreds Tens Ones
2 5 3
<em><u /></em>
<em><u>a) Between which two tens does it fall? </u></em>
Using the place values you can write 253 = 25 × 10 + 3, i.e. 25 tens and 3 ones.
From that you can write:
Then, you conclude that 253 is between 25 and 26 tens.
<u><em>b) Between which two hundreds does it fall?</em></u>
Using the same reasoning:
- 253 = 2 × 100 + 5 × 10 + 3 = 253
Conclusion: 253 is between 2 hundreds and 3 hundreds.
