00:01
All right, as we look at this situation, we have a number of different types of proportion.
00:06
So we have in this first situation, we have a 2 to a 3, and we're looking for a 10 to what number? well, 2 to 3, multiplying by 5, or 2 to 10, rather, multiplying by 5.
00:22
So 3 times 5 is 10.
00:24
Notice each of these is getting bigger.
00:26
So this is going to be a case of direct.
00:30
As we move into question 2, we have 150 kilometers.
00:36
We're traveled in 3 hours.
00:40
How far can we travel in 8 hours at the same rate? so as we cross multiply to solve, 8 times 150 divided by 3 is going to be 400 kilometers.
01:00
So again, those are the ones we're looking at.
01:03
This is, again, a direct idea in terms of our variation in proportion.
01:09
As we move on to number 3, one dozen eggs costs 72.
01:15
How much will? so we have 12 eggs cost 72.
01:21
We're looking to figure out how many 8 eggs cost.
01:27
Well, in this instance, we're looking at 2 thirds of that number.
01:30
2 thirds of this number is going to be 48p.
01:37
All right.
01:39
Again, in this, we're looking at a direct relationship.
01:43
As we look at the next situation, we have 10 men can paint a second floor of a building in 3 days.
01:54
We're looking to figure out how long it would take 6 men to do the same work.
02:01
My apologies, we're going to reset this next one.
02:03
So 1 tenth of a job, we're looking at the same rate.
02:08
So 1 tenth of the job is completed in 3 days.
02:14
We're going to, again, keep this rate because we have 10 men here...
