Question

What is representation of a division of a number; a part of a whole.

Answer 1

A division of a number or a part of a whole is represented by fractions and percentages. Dividing by a number is the same as multiplying by its reciprocal. Fractions and percentages provide a way to express quantities relative to the whole or to other quantities.

Step-by-step explanation:

The representation of a division of a number or a part of a whole is most commonly seen in mathematics through fractions and percentages. A fraction can be written as a/b, where a is the numerator indicating the number of parts we are considering, and b is the denominator indicating how many parts the whole is divided into.

The concept of numerical prefixes is applied to units in our measurements, where they represent fractions or multiples of the base units, making it easier to work with the quantities.

These mathematical principles help us understand the relationship between parts and the whole, giving us mechanisms for expressing one quantity relative to another. Understanding fractions, percentages, and the operation of division is fundamental to numerical literacy.

Answer 2

A part of a whole can be represented in three ways:

1. as a percentage - out of one hundred with the symbol % NOTE: this can be the part used or the part remaining.

2. As a ratio - in the format x:y. NOTE : This is actually x: whole - x (not x:whole)

3. As a fraction in the format x/y . NOTE: Here y is the whole
