Question

Evan used base-10 blocks to model the product of 3 and 0.51.

Answer 1

Base 10 blocks are used to perform arithmetic operations.

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:

$\mathbf{3 \times 0.51}$

Express 0.51 as 0.5 + 0.01

$\mathbf{3 \times 0.51 = 3 \times (0.5 + 0.01)}$

• 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.
