1
400
The 4 is in the hundreds column, so its value is 400.
2
305
3 hundreds = 300, 0 tens = 0, 5 ones = 5. Together that makes 305.
3
456
356 + 100 = 456. The hundreds digit goes from 3 to 4.
4
False
680 has 6 hundreds, 8 tens and 0 ones. The 8 is in the tens column, not ones.
5
305, 350, 503, 530
305 < 350 < 503 < 530. Always compare the largest place value column first.
6
8 tens
In 487, the 8 is in the tens column so it represents 8 tens (or 80).
7
910, 901, 199, 190, 109
910 > 901 > 199 > 190 > 109. Compare hundreds first, then tens.
8
370
400 - 30 = 370. Think of 400 as 300 + 100. Then 100 - 30 = 70, so the answer is 300 + 70 = 370.
9
712
712 has 7 in the hundreds column. In 127 the 7 is in the ones, in 271 it is in the tens, and in 907 it is in the ones.
10
300
The tens digit is 4, so we round down to 300.
