When the US Air arena is filled up to 80% capacity, it holds 13,600 people. How many would it hold when completely filled?
ratio..
80%:13600 ppl
100%:17000 ppl
multiply 80 by 1.25 to make it 100, then multiply 13600 by 1.25 to get 17000.
You can also divide 13,600 by 80% (0.8), which will give you 17,000. Both methods use rules of solving ratios.
To find out how many people the US Air arena would hold when completely filled, we can use the given information about the capacity at 80% and use ratios to calculate the capacity at 100%.
First, let's set up the ratio using the information given:
80% capacity = 13,600 people
100% capacity = ?
Our ratio will be: 80% to 100% = 13,600 to ?
To find the capacity at 100%, we can use either of the following methods:
Method 1: Multiplication
We can multiply 80 by 1.25 to make it 100, and then multiply 13,600 by 1.25 to get the capacity at 100%.
80% * 1.25 = 100%
13,600 people * 1.25 = Capacity at 100%
Therefore, the US Air arena would hold 17,000 people when completely filled.
Method 2: Division
Alternatively, we can divide the known capacity at 80% (13,600) by 80% (0.8) to find the capacity at 100%.
13,600 people รท 0.8 = Capacity at 100%
Again, the result is 17,000 people.
Both methods use rules of solving ratios, and you will arrive at the same answer of 17,000 people for the capacity of the US Air arena when completely filled.
