Solving for the Ratio A:B:C using Common Multiples and K Values

In mathematical problem-solving, ratios and proportions are essential concepts. This article will guide you through solving for the ratio A:B:C when given specific conditions, including using common multiples and K values. We will illustrate several scenarios where the problems are slightly modified but the core method remains consistent.

Solving for A:B:C when 2A 3B 8C

The first problem presents the relationship between A, B, and C: 2A 3B 8C k. To find the ratio of A:B:C, we need to determine the values of A, B, and C in terms of k and then express these values in their simplest form. Let's start by solving for A, B, and C.

Mathematically,
2A k
A k/2

3B k
B k/3

8C k
C k/8

Now, we want to find the ratio of A:B:C. To do this, we divide each term by the smallest value of C:

A:B:C (k/2) : (k/3) : (k/8)
(4/1) : (8/3) : 1

Thus, the ratio of A:B:C is 4:8/3:1.

Solving for A:B:C with a Different Relationship

The next problem has a slightly different relationship: 2A 3B 5C k. We follow a similar process to solve for A, B, and C:

2A k
A k/2

3B k
B k/3

5C k
C k/5

Expressing the ratio A:B:C in terms of k, we get:

A:B:C (k/2) : (k/3) : (k/5)
(15k/30) : (10k/30) : (6k/30)
15k : 10k : 6k

Which simplifies to 15:10:6.

Another Example with 2A 3B 4C

Consider the problem with 2A 3B 4C k. Let's find the ratio A:B:C step-by-step:

2A k
A k/2

3B k
B k/3

4C k
C k/4

A:B:C can be written as:

A:B:C (k/2) : (k/3) : (k/4)
6 : 4 : 3

Thus, the ratio of A:B:C is 6:4:3.

These examples illustrate the application of common multiples and K values in finding and simplifying the ratio A:B:C. Whether it's through direct calculation or simplification using a common denominator, the method remains consistent across different scenarios.
