Answer :
Using proportions, it is found that the equivalent ratio to six-seconds would be of 3 to 1.
What is a proportion?
A proportion is a fraction of total amount, and the measures are related using a rule of three.
In this problem, six quarters are equivalent to two pennies. Dividing into two groups, there would be a penny in each group, and we want to find the amount of quarters.
The rule of three is:
2 pennies - 6 quarters
1 penny - x quarters
Applying cross multiplication:
[tex]2x = 6[/tex]
[tex]x = \frac{6}{2}[/tex]
[tex]x = 3[/tex]
The equivalent ratio to six-seconds would be of 3 to 1.
