Introduction

When comparing numbers, it's essential to understand the different forms in which they can be represented. In this article, we will explore the comparison of fractions, percentages, and decimals. We will examine the given options and determine which list is in order from smallest to largest.

Understanding the Forms of Numbers

Fractions

Fractions are a way of representing a part of a whole. They consist of a numerator (the top number) and a denominator (the bottom number). For example, the fraction $\frac{1}{4}$ represents one part out of four equal parts.

Percentages

Percentages are a way of representing a value as a fraction of 100. They are often used to express a proportion or a rate. For example, the percentage 14% represents 14 parts out of 100 equal parts.

Decimals

Decimals are a way of representing a number using a point (.) to separate the whole number part from the fractional part. For example, the decimal 1.4 represents one and four-tenths.

Comparing the Options

Option A: $\frac{1}{4}, 14\%, 1.4$

To compare these numbers, we need to convert them to a common form. Let's convert the percentage to a decimal by dividing by 100:

14% = 0.14

Now, let's compare the numbers:

$\frac{1}{4}$ = 0.25
0.14
1.4

In this order, the numbers are not in order from smallest to largest.

Option B: $1.4, \frac{1}{4}, 14\%$

Let's convert the percentage to a decimal by dividing by 100:

14% = 0.14

Now, let's compare the numbers:

1.4
0.25
0.14

In this order, the numbers are not in order from smallest to largest.

Option C: $14\%, \frac{1}{4}, 1.4$

Let's convert the percentage to a decimal by dividing by 100:

14% = 0.14

Now, let's compare the numbers:

0.14
0.25
1.4

In this order, the numbers are not in order from smallest to largest.

Option D: $1.4, 14\%, \frac{1}{4}$

Let's convert the percentage to a decimal by dividing by 100:

14% = 0.14

Now, let's compare the numbers:

1.4
0.14
0.25

In this order, the numbers are in order from smallest to largest.

Conclusion

In conclusion, the correct answer is Option D: $1.4, 14\%, \frac{1}{4}$ . This list is in order from smallest to largest. It's essential to understand the different forms in which numbers can be represented and to convert them to a common form when comparing them.

Tips and Tricks

When comparing fractions, percentages, and decimals, it's essential to convert them to a common form.
