Wouldn’t you just find one-fourth of all the populations, and add them together? So you get 1/4(150,000) + 1/4(100,000) + 1/4(20,000). But that would be looong. So you use the Distributive Property…take out a common factor. Here, there’s one fourth. So you’d take it out, and it’ll look like this: 1/4(150,000 + 100,000 + 20,000).

If you want to get fancy, you can take out more factors than just the 1/4, but I don’t see any need for that.

150,000/4= 37,500 people died in Paris.

100,000/4 =25,000 people died in Venice

20,000/4= 5,000 people died in Nurenberg.

to figure this problem out, you can also do 1/4 which equals .25 then do it on a calculator

150 + 20 + 100 = 270

that is 270,000 people.

now find one fourth of them

1/4 * 270,000 that is, (270,000 / 4)

im sure u can figure out the answer from there.
