The distributive property means to distribute the number outside the parentheses across all the numbers within the parentheses.
ie. 5(100+20+9) => 5*100+5*20+5*9 => 500+100+45
Solve from there.

This becomes 5(100) + 5(20) + 5(9)
500 + 100 + 45 = 645

5(100 + 20 + 9)
= 5 (129)
= 645
That's probably the simplest way to find the answer, but if you want to use the distributive property throughout, you can break it down a slightly different way:
5(100) + 5(20) + 5(9)
= 500 + 100 + 45
= 645
Hope that helps.

This is what you do: 5(100) + 5(20) + 5(9)
500 + 100 + 45 = 645

You could complete this problem in one of two ways:
First, you could distribute the 5 to each of the numbers:
5*100 5* 20 5*9
and then add up the results.
500 + 100 + 45 = 645
Or, you could add up all the numbers in the parentheses and then times their sum by 5.
100 + 20 + 9 = 129
129*5 = 645

5(100 + 20 + 9)
By the distributive property, multiply each term summed in the brackets by 5, as follows:
5(100) + 5(20) + 5(9)
Evaluate each one, and add
500 + 100 + 45
Which is equal to
645
Note that math is math is math, and this should evaluate to 645 no matter what method you use.
5(100 + 20 + 9)
Had we added the terms in brackets first and then multiplied, we would get
5(129)
which is
645

5(100 + 20 + 9)
Do the math inside the parentheses first:
5 (129) = 645

5(100 + 20 + 9) = (5 * 100) + (5 * 20) + (5 * 9)
5 * 129 = 500 + 100 + 45
645 = 645
Answer: (5 * 100) + (5 * 20) + (5 * 9)
