10. Birth/death rate
Take birth or death rate and x 1,000

11. Practice – On left side Number 1
Take birth or death rate and x 1,000
# births: 3,250
Population: 223,000

12. Answer #1: Practice – On left side
# births: 3, Population: 223,000
3,250 / 223,000 =
x 1000 = 14.57% or 14.6%

13. Practice – On left side Number 2
Take birth or death rate and x 1,000
# deaths: 2,560
Population: 279,000

14. Answer #2: Practice – On left side
# deaths: 2,560
Population: 279,000
2,560 / 279,000 =
x 1,000 = 9.17% or 9.2%

15. practice – On left side Number 3
Take birth or death rate and x 1,000
# births: 3,250
Population: 125,625

16. Answer #3: Practice – On left side
# deaths: 3,250
Population: 125,625
3,250 / 125,625 =
x 1,000 = 25.87% or 25.9%
