Have you ever been stuck on a problem? Take a look at this dilemma.

Instead of letter writing, Carmen had to complete some math homework. She is working on comparing negative fractions and decimals. This is exactly where she got stuck.

"I am never going to get this done," she muttered under her breath at the kitchen table.

Here is the problem she is stuck on.

Do you have any idea how to compare these two?

Well, you are in luck.

**This Concept is all about comparing negative fractions and decimals. You will know how to help Carmen by the end of the Concept.**

### Guidance

We have been working with the set of integers. ** Integers** are positive and negative whole numbers. However, we can also have positive and negative fractions and decimals.

**These positive and negative fractions and decimals are not members of the set of integers.** They are ** rational numbers** and you will work more with them next year.

**That being said, we can still order and compare positive and negative decimals and fractions.**

**How do we do this?**

Let's take a look.

If we want to compare negative one-half and negative three-fourths, we have to think of which fraction is closer to zero. Negative one-half is smaller than negative three-fourths. Remember when we work with negative numbers that the smaller negative number is greater.

**We can use a number line to help us here too.**

Here is another way to look at these numbers using a number line. You can see here that

**What about negative and positive decimals?**

Negative and positive decimals can be compared just like fractions. Decimals are a part of a whole just like fractions are a part of a whole. Therefore, a positive decimal is ALWAYS greater than a negative decimal. When you have two negative decimals, the one closer to zero is always greater. The farther a negative decimal is from zero, the smaller its value.

.45 ____ -.18

A positive number is always greater than a negative number. This also holds true for decimals and fractions.

.45 > -.18

-.29 ____ -.56

The smaller the number the closer it is to zero.

-.29 > -.56

Now it’s time for you to practice. Compare the following negative and positive decimals.

#### Example A

**-.98 ____ -.88**

**Solution: <**

#### Example B

**Solution: >**

#### Example C

**.67 ____ -.67**

**Solution: >**

Here is the original problem once again.

Instead of letter writing, Carmen had to complete some math homework. She is working on comparing negative fractions and decimals. This is exactly where she got stuck.

"I am never going to get this done," she muttered under her breath at the kitchen table.

Here is the problem she is stuck on.

Do you have any idea how to compare these two?

First, we have to write them both as fractions. Let's convert -.38 to a fraction.

Now we need to write them so they have the same denominator. Let's change negative two - fifths to a fraction with a denominator of 100.

Next we can compare.

**This is the answer.**

### Vocabulary

Here are the vocabulary words in this Concept.

- Integers
- the set of whole numbers and their opposites

- Negative Numbers
- numbers that are less than zero

- Positive Numbers
- numbers that are greater than zero

- Zero
- is a part of the set of integers, but is neither positive or negative

### Guided Practice

Here is one for you to try on your own.

Compare

**Answer**

Remember, the closer a value is to zero, the greater the value. Remember this with integers?

This is a true statement.

We must keep this in mind when working with negative fractions too.

Negative six - sevenths is a larger fraction. Because it is negative, it is farther away from zero. It is the smaller value in this case.

**This is the answer.**
