$$\frac{ n }{ 18 } = \frac{ 5 }{ 9 }$$

photon336 · Answer

we need to isolate n first by multiplying both sides by 18 like this. 

$$\frac{ n }{ 18 }*\frac{ 18 }{ 1 } = \frac{ 5 }{ 9 }*18$$

photon336 · Answer

now as you can see, when we do this n is now by itself  so now 

we're left with 

$$n = \frac{ 5 }{ 9 }*\frac{ 18 }{ 1 }$$

photon336 · Answer

so @HarleyQuinn98 all you need to do is multiply 18 by 5/9 

$$\frac{ 5 }{ 9 }*\frac{ 18 }{ 1 } = \frac{ 90 }{ 9 } = 10$$

and we can plug this back in to check our answer too

n = 10 

and we find that these two are equal.

$$\frac{ 10 }{ 18 } = \frac{ 5 }{ 9 }$$
