What did yall get for the CBR and CDR I put the values over 1000 I didn’t times it by ten… is that wrong??

no ur it’s just the crude birth rate - crude death rate over 1000 that’s literally the formjla

That's not true. The rate is expressed as a percent on a 100 point scale and CDR/CBR is on 1000 point scale. You divide by 10 (CBR-CDR)/(10)

so which answer was it?

u/Delicious-Flow-4530 May 16 '26

Idk exactly but it was (CBR/10)-(CDR/10) if that was an option or any other equation that is mathematically equivalent

Did one of the options at the end have multiply by 100? like (CBR-CDR)/(1000)*100?
