Part B: Fill in the Blank
Write the correct answer on each line.
1. I have 3 hundreds, 4 tens, and 6 ones. I am 346.
3 hundreds plus 4 tens plus 6 ones equals 300 + 40 + 6, which is 346.
2. I have 7 hundreds, 0 tens, and 0 ones. I am 700.
7 hundreds alone makes 700, since tens and ones both add nothing.
3. I am 10 more than 432. I am 442.
432 plus 10 equals 442, since only the tens digit changes from 3 to 4.
4. I am 100 less than 519. I am 419.
519 minus 100 equals 419, since only the hundreds digit drops from 5 to 4.
5. I have 8 in the hundreds place, 2 in the tens place, and 1 in the ones place. I am 821.
8 hundreds, 2 tens, and 1 one combine as 800 + 20 + 1, which is 821.
