Using proportions, it is found that the equivalent ratio to six-seconds would be of 3 to 1.
<h3>What is a proportion?</h3>
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 <em>rule of three</em> is:
2 pennies - 6 quarters
1 penny - x quarters
Applying cross multiplication:
The equivalent ratio to six-seconds would be of 3 to 1.

Answer with explanation:
Number of Letters from which we have to make four-letter passwords
={A,B,C,D,E,F,G}=7
Since repetition of digit is not allowed.In Permutation order of arrangement is Important,while in combination order of arrangement is not Important.
Out of seven letters we have to select four letters, keeping in mind the order of Alphabets.So, we will use the concept of Permutation.
Number of ways of arrangement,that is to make four letter password from 7 Alphabets
So, total number of ways of making password from 7 alphabets=840 ways
Second Method⇒
Since repetition of alphabets is not allowed, first Alphabet can be chosen in 7 ways , second alphabet can be chosen in 6 ways, third alphabet can be chosen in 5 ways, fourth alphabet can be chosen from four alphabets.
So, total number of ways of making four letter password
=7×6×5×4
= 840 ways
