Answer 3

To calculate the products, we can use the property of multiplication that states:

$a \times b = (a \times 100) - (a \times c)$

where $c$ is the number subtracted from 100 to get the multiplier. In this case, since we're multiplying by 99, $c = 100 - 99 = 1$.

Let's calculate the products:

1. $509 \times 99 = (509 \times 100) - (509 \times 1) = 50,900 - 509 = 50,391$
2. $304 \times 99 = (304 \times 100) - (304 \times 1) = 30,400 - 304 = 30,096$
3. $206 \times 99 = (206 \times 100) - (206 \times 1) = 20,600 - 206 = 20,394$
4. $313 \times 99 = (313 \times 100) - (313 \times 1) = 31,300 - 313 = 30,987$

Therefore:

• $509 \times 99 = 50,391$
• $304 \times 99 = 30,096$
• $206 \times 99 = 20,394$
• $313 \times 99 = 30,987$
