Select all that apply. Which of the following shows that 5/6 = 15/18 is a proportion? 5 • 15 = 6 • 18
5 • 18 = 6 • 15
5.6/6.3 = 5/18
5+10/6+12 = 15/18

5 · 18 = 6 · 15

Step-by-step explanation:

5/6 = 15/18

If this is proportional, then if we flip it, it should work,

To do this, we'll need to do the opposite to both sides

Which we'll multiply 15 by that 6 under the 5, and the 5 by the 18 which was under the 15

So;

5 · 18 = 15 · 6

Which can be rewritten as

5 · 18 = 6 · 15

Hope that helps :)
