Prepare to discuss a time when representing 241 as 2 hundreds, 3 tens, and 11 ones might be helpful.
5 hundreds + 7 ones + 2 tens = 527
1 hundred + 1 ten + 17 ones = 1 hundred +
4 hundreds + 15 tens + 3 ones =
4 hundreds + 3 tens + 7 ones = 3 hundreds +
7 hundreds + 8 tens + 4 ones = 7 hundreds + 7 tens +
6 hundreds + 9 ones = 5 hundreds +
2 hundreds + 9 tens + 17 ones =
3 hundreds + 1 ten + 5 ones = 2 hundreds + 10 tens +
