By using a 3-simple rule, we will see that 30% of the science club is on the Spanish club.

How to find the percentage of science club students is in the Spanish club?

First, we know that there are 18 girls and 12 boys in the science club, then there are 12 + 18 = 30 students on the science club, this will be the 100%.

30 = 100%.

And there are 4 girls and 5 boys in the Spanish club, then there are 4 + 5 = 9 students on the Spanish club, let's say that this number represents a percentage X.

9 = X

Then we have the equations:

30 = 100%

9 = X

To find the value of X, we can take the quotient of these two equations:

9/30 = X/100%

Solving for X, we get:

(9/30)*100% = X = 30%

Then we can conclude that 30% of the science club is in the Spanish club.
