Answer 1

So, let's try something similar, but with smaller numbers. Let's say that we had 10 registered votes, and half of them were expected to vote. How many would that be?

Answer 2

5.

Answer 3

Right, and we can get that by multiply 10 by 1/2
because that is how we figure out what half of a number is. By multiply it by 1/2
So we just need to do the same thing for 8.45X10^5
we need to multiply it by 1/2

So what would 1/2 x 8.45 x 10^5 be?
