Answer 1

The base-ten blocks is used to represent the place values of a number.

Shawn requires 13 blocks, 4 flats and 5 longs.

In base-ten blocks;

• Block = Thousands
• Flat = Hundreds
• Long = Tens

So, first, we divide 13450 by 1000 to get the number of blocks

$Block = \frac{13450}{1000}$

$Block = 13.450$

Remove the decimal part

$Block = 13$

Multiply the decimal part by 1000, to get the remaining value

$n = 0.450 \times 1000$

$n = 450$

Divide 450 by 100, to get the number of flats

$Flats = \frac{450}{100}$

$Flats = 4.5$

Remove the decimal part

$Flats = 4$

Multiply the decimal part by 100, to get the remaining value

$n = 0.5 \times 100$

$n = 50$

Divide 450 by 10, to get the number of longs

$Long = \frac{50}{10}$

$Long = 5$

Hence, Shawn requires 13 blocks, 4 flats and 5 longs.
