00:00My friends are asking if you can buy 15 t-shirts for 90 lira, so how much would it cost to buy 25 t-shirts?
00:06So, what are the friends like now?
00:07You can buy 15 t-shirts for 90 TL.
00:13If there are 25, let's call it X.
00:17Now, as you can see, friends, what does 90 lira represent the total price of the t-shirts?
00:23There's a ratio to the total number of t-shirts, right guys?
00:26Yes.
00:27What kind of ratio is this, guys?
00:28Direct proportion.
00:30How does this happen in this situation?
00:32The ratio of 15 to 90 must be equal to the ratio of X to 25.
00:39So, in situations like this, when we talk about direct proportionality and establish a relationship like this, it has to be this way.
00:47In this case, if we find our X from here, then dividing by 5 is 3, and dividing by 5 is 5, right?
00:551, 30.
00:57When we apply the following condition, we find that our X is 150 TL.
