Answer:
The ratio that compares the championships won by Australia to the total number won by the United States is equal to
Step-by-step explanation:
Observing the graph
we know that
The championships won by Australia are 6
The championships won by the United States are 15
To find out the ratio, divide the championships won by Australia by the total number won by the United States.
so
Simplify
Divide by 3 boths (numerator and denominator)
Convert to percentage
that means
For every 2 championships won by Australia the United States won 5
or
The championships won by Australia are 40% of the championships won by the United States
This is what the following graph would look like:
Answer:
