(a)
Interpretation:
The equivalency and both conversion factor a) minutes and seconds is to be stated.
Concept introduction:
Equivalency is defined as the two quantities that are equivalent in value. For example: 0.025 furlong is equal to 1 rod. In this case, furlong and rod represent the same physical length but expressed in various units. When an equivalency is denoted as a fractional value it is called ‘conversion factor’. Moreover, two conversion factors result from each equivalency.

Answer to Problem 19E
The equivalency of a) minutes and seconds is
Conversion factors of a) minutes and seconds are given by;
Explanation of Solution
The two quantities that are equivalent in value is denoted as equivalence. For example:
In the expression (1), the conversion factor
A proportionality constant, m is inserted to convert a proportionality into an equality. Such as,
Given expression;
a) Minutes and seconds
Based on the above discussion the equivalency and conversion factors are states as follows;
The equivalency of a) minutes and seconds is
Conversion factors of a) minutes and seconds are given by;
Thus, the equivalency and both conversion factor a) minutes and seconds is to be stated
(b)
Interpretation:
The equivalency and both conversion factor b) inches and feet is to be stated
Concept introduction:
Equivalency is defined as the two quantities that are equivalent in value. For example:

Answer to Problem 19E
The equivalency of b) inches and feet is
Conversion factors of b) inches and feet are given by;

Conversion factors of inches and feet are given by;
Thus, the equivalency and both conversion factor inches and feet is to be stated
(c)
Interpretation:
The equivalency and both conversion factor c) dollars and cents is to be stated
Concept introduction:
Equivalency is defined as the two quantities that are equivalent in value. For example:

Answer to Problem 19E
The equivalency of c) dollars and cents is 1 dollar = 100 cents
Conversion factors of c) dollars and cents are given by;
Explanation of Solution
The two quantities that are equivalent in value is denoted as equivalence. For example:
In the expression (1), the conversion factor
A proportionality constant, m is inserted to convert a proportionality into an equality. Such as,
Given expression;
c) dollars and cents
Based on the above discussion the equivalency and conversion factors are states as follows;
The equivalency of c) dollars and cents is 1 dollar = 100 cents
Conversion factors of c) dollars and cents are given by;
Thus, the equivalency and both conversion factor dollars and cents is to be stated
