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
![(6)/(15)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/56equbowbxg2eo9kecsfoti1n7r1s4ggcr.png)
Simplify
Divide by 3 boths (numerator and denominator)
![(2)/(5)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/t0uv673spbc3c31ajeld1inwaddg10eja3.png)
Convert to percentage
![(2)/(5)=0.40*100=40\%](https://img.qammunity.org/2020/formulas/mathematics/middle-school/ca13f01vfblxbnc66o1hg4lj2hi979cbqj.png)
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
