The population of Vietnam is approximately 4 times the population of Australia. The population of Brazil is approximately 8 times the population of Australia. The population of Australia is approximately 5 times the population of New Zealand. About how many times larger than the population of New Zealand is population of Vietnam?
first, I change the contries to variables Vietnam - v Australia - a brazil - b new Zealand - n v=4a b=8a a=5n brazil is not needed plug in 5n for a v=4(5n) v=20n Vietnam would actually be larger if it takes 20 new zealands for 1 vietnam
