Answer:
10.5 : 1
Step-by-step explanation:
We are given that 84% of the group of people from Portugal, Spain and France are from Portugal
That means the remaining number of people which is (100-84) percent = 16% are from both Spain and France
Since number from Spain = number from France, the number from Spain = 16/2 = 8%
The ratio number from Portugal : number from Spain is
84:8
Dividing both sides of the ratio by 8 gives us the ratio in the form n:1
84/8 = 10.5
8/8 = 1
84:8 is equivalent to 10.5 : 1
