Darcy uses place-value blocks to show a number. she use 4 thousand blocks and 5 hundred blocks .whats is the number? how can she uses place-value blocks to show the number? explain?

The number is 4,500.00

From the decimal point, moving to the left, the place values would be ONES, TENS, HUNDREDS, THOUSANDS, TENS THOUSAND, HUNDREDS THOUSANDS.

Since Darcy placed 4 in the thousands blocks, it should look like this 4,000.

Then 5 should be in the hundred block; thus, 500.

Adding both numbers resulted to 4,500. Four thousand five hundred only.
