10/n = 18/27 what is n?

Well, to understand what "n" is, we have to understand the relation between 18 and 27.

If we divide by 9, we'll notice that 18/27 simplifies to 2/3.

So, let's apply this to 10/n

10 over n must be the same ratio of 2/3.

10/2 is 5.

5*3 = 15.

n = 15.

Alternatively, cross multiply and solve.

10/n = 18/27

n will multiply with 18, 10 with 27.

18n = 270

/18 / 18

n = 15

N = 10*27 / 87 = 270/18 = 15
