Chapter 2, Problem 2.75EP

(a)

Interpretation Introduction

Interpretation:

The equation $\text{1}\text{dozen}\text{=}\text{12}\text{objects}$ will generate exact or inexact set of conversion factor has to be given.

Concept Introduction:

Numbers are classified into two, namely the exact numbers and the inexact numbers.  Exact numbers appear exactly with no uncertainty and occur during counting, with definite numbers and with no decimal number.  While inexact numbers has some uncertainty and occurs during any kind of measurement that is made. Measurements made with numerical are impossible to be so exact. Hence numerical measurements are always inexact.

(b)

Interpretation Introduction

Interpretation:

The equation $\text{1}\text{kilogram}\text{=}\text{2}\text{.2}\text{pounds}$ will generate exact or inexact set of conversion factor has to be given.

(c)

Interpretation Introduction

Interpretation:

The equation $\text{1}\text{minute}\text{=}\text{60}\text{seconds}$ will generate exact or inexact set of conversion factor has to be given.

(d)

Interpretation Introduction

Interpretation:

The equation $\text{1}\text{millimeter}\text{=}{\text{10}}^{\text{-3}}\text{meters}$ will generate exact or inexact set of conversion factor has to be given.
