Answer 1

To determine which expressions are equivalent to 3.64, we can evaluate each option:

1. **36.4 × 10**: This equals 364, which is NOT equivalent to 3.64.
2. **0.0364 × 100**: This equals 3.64, which IS equivalent to 3.64.
3. **(3 × 1) + (6 × 0.1) + (4 × 0.01)**: This breaks down as follows:
- 3 × 1 = 3
- 6 × 0.1 = 0.6
- 4 × 0.01 = 0.04
Thus, 3 + 0.6 + 0.04 = 3.64, which IS equivalent to 3.64.
4. **[(3 × 1) + (6 × 0.1) + (4 × 0.01)] × 100**: Since we determined that (3 × 1) + (6 × 0.1) + (4 × 0.01) = 3.64, multiplying this by 100 gives 364. Therefore, this is NOT equivalent to 3.64.
5. **36.4 ÷ 10**: This equals 3.64, which IS equivalent to 3.64.

Therefore, the THREE expressions that are equivalent to 3.64 are:

- **0.0364 × 100**
- **(3 × 1) + (6 × 0.1) + (4 × 0.01)**
- **36.4 ÷ 10**
