Title: Comparing Fractions with Different Denominators

Subtitle: A Comprehensive Guide to Understanding Fractions

Introduction

Fractions are an important part of mathematics, and they can be used to compare different values. Comparing fractions with different denominators can be tricky, but with the right tools and understanding, it can be done. In this guide, we’ll discuss the basics of comparing fractions with different denominators, how to do it, and how to use it in everyday life.

Body

When comparing fractions with different denominators, the first step is to understand what the denominator represents. The denominator is the number at the bottom of the fraction, and it represents the number of equal parts that the fraction is divided into. For example, if a fraction has a denominator of 4, it is divided into four equal parts.

Once you understand the denominator, you can then compare the fractions. To do this, you need to find a common denominator. A common denominator is a number that is divisible by both of the fractions’ denominators. For example, if you have two fractions, one with a denominator of 4 and one with a denominator of 5, the common denominator would be 20.

Once you have a common denominator, you can then compare the fractions. To do this, you need to find the equivalent fraction for each fraction. An equivalent fraction is a fraction with the same value, but different numerators and denominators. To find the equivalent fraction, you need to multiply the numerator by the denominator of the other fraction, and divide the result by the denominator of the fraction you are comparing.

For example, if you have two fractions, one with a numerator of 1 and denominator of 4, and one with a numerator of 2 and denominator of 5, you can find the equivalent fraction of the first fraction by multiplying 1 by 5 and dividing the result by 4. This gives you an equivalent fraction of 5/20. You can then compare the fractions by comparing their numerators. In this example, the fraction with the numerator of 2 (2/5) is greater than the fraction with the numerator of 1 (5/20).

Examples

Let’s look at a few examples of how to compare fractions with different denominators.

Example 1:

You have two fractions, one with a numerator of 3 and denominator of 6, and one with a numerator of 4 and denominator of 8.

To find the common denominator, you need to find a number that is divisible by both 6 and 8. The common denominator in this example is 24.

To find the equivalent fraction of the first fraction, you need to multiply 3 by 8 and divide the result by 6. This gives you an equivalent fraction of 8/24.

To compare the fractions, you compare their numerators. In this example, the fraction with the numerator of 4 (4/8) is greater than the fraction with the numerator of 3 (8/24).

Example 2:

You have two fractions, one with a numerator of 5 and denominator of 9, and one with a numerator of 7 and denominator of 10.

To find the common denominator, you need to find a number that is divisible by both 9 and 10. The common denominator in this example is 90.

To find the equivalent fraction of the first fraction, you need to multiply 5 by 10 and divide the result by 9. This gives you an equivalent fraction of 50/90.

To compare the fractions, you compare their numerators. In this example, the fraction with the numerator of 7 (7/10) is greater than the fraction with the numerator of 5 (50/90).
