Introduction

Understanding the relationship between whole numbers and their ratios when their sum is a fixed value, such as 64, can provide valuable insights into number theory and proportional reasoning. This article explores how to find the ratio of two whole numbers whose sum is 64 and discusses the methodology behind solving such problems efficiently. Whether you are a student, a teacher, or someone with a keen interest in mathematics, this guide will help you grasp the concept and solve related problems with ease.

Solving the Problem of Ratios

To find the ratio of two whole numbers whose sum is 64, we can represent the numbers as (x) and (y). The basic equation that satisfies this condition is:

[text{Equation 1:} quad x y 64]

From this equation, we can derive the ratio of (x) to (y), given by:

[text{Ratio} frac{x}{y}]

a) Expressing (y) in terms of (x), we get:

[text{Equation 2:} quad y 64 - x]

Substituting this expression for (y) into the ratio, we obtain:

[text{Ratio} frac{x}{64 - x}]

This equation shows that for different values of (x), we can find various ratios. Here are some examples:

If (x 32), then (y 32) and the ratio is (1:1). If (x 40), then (y 24) and the ratio is (frac{40}{24} frac{5}{3}). If (x 48), then (y 16) and the ratio is (frac{48}{16} 3:1).

As you can see, by choosing different values for (x) between 1 and 63, you can find a diverse range of ratios. This flexibility allows for an exploratory approach to learning about ratios and proportions.

Generalizing the Solution

The problem of finding a specific ratio is often presented in multiple-choice (MCQ) questions, which can be solved quickly using back calculation. Here are some example options:

17:2 2 2 7:6 33:1 48:7

The question hints that the correct answer is 64 when you sum the numbers in the ratio and then multiply the result by 16. Let's validate this with a simple example:

If the ratio is 3:1, then the numbers are 3 and 1. Their sum is (3 1 4), and multiplying this sum by 16 gives (4 times 16 64).

This method works for any valid ratio, as the sum of (x) and (y) will always be 64, and this fact is often used in classic mathematics problems involving ratios.

Identifying Different Pairs and Their Ratios

When the two numbers are 24 and 40, the ratio is 3:5. This example extends the concept further by enumerating several pairs and their corresponding ratios. Here are some detailed examples:

1 and 63: (1 63 64), ratio is (1:63). 2 and 62: (2 62 64), ratio is (1:31). 3 and 59: (3 59 64), ratio is (3:59). 4 and 60: (4 60 64), ratio is (1:15). 5 and 59: (5 59 64), ratio is (5:59). 6 and 58: (6 58 64), ratio is (3:29). ( ( 9 and 55: (9 55 64), ratio is (9:55). 10 and 54: (10 54 64), ratio is (5:27). 11 and 53: (11 53 64), ratio is (11:53). 12 and 52: (12 52 64), ratio is (3:13). 13 and 51: (13 51 64), ratio is (13:51). 14 and 50: (14 50 64), ratio is (7:25). 15 and 49: (15 49 64), ratio is (15:49). 16 and 48: (16 48 64), ratio is (1:3). 17 and 47: (17 47 64), ratio is (17:47). 18 and 46: (18 46 64), ratio is (9:23). 19 and 45: (19 45 64), ratio is (19:45). 20 and 44: (20 44 64), ratio is (5:11). 21 and 43: (21 43 64), ratio is (21:43). 22 and 42: (22 42 64), ratio is (11:21). 23 and 41: (23 41 64), ratio is (23:41). 24 and 40: (24 40 64), ratio is (3:5). 25 and 39: (25 39 64), ratio is (25:39). 26 and 38: (26 38 64), ratio is (13:19). 27 and 37: (27 37 64), ratio is (27:37). 28 and 36: (28 36 64), ratio is (7:9). 29 and 35: (29 35 64), ratio is (29:35). 30 and 34: (30 34 64), ratio is (15:17). 31 and 33: (31 33 64), ratio is (31:33). 32 and 32: (32 32 64), ratio is (1:1).

Through these detailed examples, we see the variety of ratios possible when the sum of two whole numbers is 64. By exploring different values for (x) and (y), we can gain a deeper understanding of the relationship between the two numbers and their ratios.
