What is 3/4ths of 1/3rd? A Comprehensive Guide

Introduction

In the vast realm of mathematics, fractions play a pivotal role in representing and manipulating parts of a whole. One common question that often arises is "What is 3/4ths of 1/3rd?" This看似简单的问题涉及到分数运算的基本原则，但为了透彻地理解其含义和应用，需要仔细的探索。

Understanding Fractions

Definition: A fraction is a mathematical expression that represents a part of a whole. It consists of two parts: the numerator (top number) and the denominator (bottom number). The numerator indicates the number of equal parts being considered, while the denominator represents the total number of equal parts in the whole.

Example: The fraction 1/3 represents one part out of three equal parts.

Multiplication of Fractions

To find 3/4ths of 1/3rd, we need to multiply the two fractions:

(3/4) x (1/3) = (3 x 1) / (4 x 3) = 3/12

Simplifying the fraction further, we get:

3/12 = 1/4

Therefore, 3/4ths of 1/3rd is equal to 1/4.
