Which shows 4,327 in expanded form?
$4,000 + 30 + 2 + 7$
$400 + 300 + 20 + 7$
$4,000 + 300 + 20 + 7$
$4,000 + 200 + 70 + 3$
Explanation
Place value chart: Thousands 4, Hundreds 3, Tens 2, Ones 7. Expanded form is 4,000 + 300 + 20 + 7. Choices A and B misplace digits; D swaps hundreds, tens, and ones.
Which choice makes the statement true? 6,482 __ 6,428
$6,482 > 6,428$
$6,482 < 6,428$
$6,482 = 6,428$
$6,428 > 6,482$

Compare from left to right using a place value chart: Thousands 6 vs 6 (same), Hundreds 4 vs 4 (same), Tens 8 vs 2 (8 is greater). So 6,482 is greater than 6,428.
