Thumbs up Manipulating Sound Pressure Level

I've performed an experiment on guitar tone - ive used a fourier analysis to find the different frequency components. The idea of this is to find the sound pressure level of the consonant intervals present in a guitar tone and compare it to the SPL of the dissonant intervals.

I have found the overall SPL of the consonant and dissonant intervals, but i'm stuck on comparing them. Would it make sense to divide two SPLs by each other? or how would i do that if not

for example, if i have 100.8 dB for all of the consonant intervals, can i just do 100.8/(overall SPL) to find the fraction of the overall SPL that is made up of "consonant" sound?

Thank you for your help!

Be careful with the decibel, it is not a straight-forward unit.
see <Wikipedia : Decibel>
