So for this problem, we are told that in ancient rome, for about 390 years, the coliseum was used as a form of entertainment.
00:12
And during that time, more than 400 ,000 people died, and more than a million animals died.
00:19
So the question is to use fraction multiplication to decide how many animals, to determine how many animals per day died during those 390 years.
00:29
So we are going to start out with our million animals.
00:43
And we're going to multiply that.
00:46
We're looking for animals per day.
00:54
So we know that there was a million animals that died in 390 years.
01:04
And our challenge now is we need to change that years to days.
01:08
So we're going to put one year on top.
01:11
And then we're going to remember at the back of our mind, that in one year, there are 365 days.
01:21
So we are going to, we can then use cancellation to cancel out years, and we'll end up with animals per day.
01:31
And the way this works is we'll take our $1 million, divide by $390, and then divide again by $365.
01:44
And so when we do that, we get approximately seven animals per day.
02:07
Officially it's 7 .02 but i think that's close enough to seven since we're dealing with an approximation to start with.
02:16
And then how many animals died per person? so we would just look at this as animals...
