Question

Create a representation of 7.42 with base ten blocks.

Answer 1

To represent the decimal number 7.42 using base ten blocks, we can break it down into its whole number and decimal parts:

1. **Whole Number Part (7)**:
- Use 7 unit cubes (representing 1 each) to show the whole number part.

2. **Decimal Part (0.42)**:
- The digit 4 in the tenths place means you need 4 rods (each representing 0.1).
- The digit 2 in the hundredths place means you need 2 flat squares (each representing 0.01).

Putting it all together, the representation of 7.42 using base ten blocks would look like this:

- **7 Units (cubes)** for the whole number part.
- **4 Rods** for the tenths.
- **2 Flats** for the hundredths.

In summary:
- **7 Unit Blocks** (1s): 7
- **4 Rods** (0.1s): 4
- **2 Flats** (0.01s): 2

This creates a visual representation of the number 7.42 using base ten blocks.
