**7. $$ 56.98 \times 1000 $$**

Multiplying by 1000 shifts the decimal point three places to the right:

$$
56.98 \times 1000 = 56980
$$

**8. $$ 24.575 \times 50 $$**

One method is to recognize that multiplying by 50 is equivalent to multiplying by 100 and then dividing by 2:

$$
24.575 \times 50 = \frac{24.575 \times 100}{2} = \frac{2457.5}{2} = 1228.75
$$

**9. $$ 2.25 \times 25 $$**

We can multiply directly:

$$
2.25 \times 25 = 2.25 \times (20 + 5) = (2.25 \times 20) + (2.25 \times 5)
$$

Calculate each term:

$$
2.25 \times 20 = 45 \quad \text{and} \quad 2.25 \times 5 = 11.25
$$

Adding these:

$$
45 + 11.25 = 56.25
$$
**7. $$ 56.98 \times 1000 = 56980 $$** **8. $$ 24.575 \times 50 = 1228.75 $$** **9. $$ 2.25 \times 25 = 56.25 $$**

7. \( 56.98 \times 1000 \) 8. \( 24.575 \times 50 \) 9. \( 2.25 \times 25 \)
