To model the product of 3 and 0.51, Evan needs 3 copies of 5 tenths and 1 hundredths.
The expression can be represented as:
[tex]\mathbf{3 \times 0.51}[/tex]
Express 0.51 as 0.5 + 0.01
[tex]\mathbf{3 \times 0.51 = 3 \times (0.5 + 0.01)}[/tex]
- 0.5 means 5 tenths
- 0.01 means 1 hundredths
- 3 means that, the above blocks are needed in three places.
Hence, Evan needs 3 copies of 5 tenths and 1 hundredths.
