Question

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?

Answer 1

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
