## The Basics of Fractions

A fraction is a number that represents a part of a whole. In other words, it is a number that is not a whole number. When we talk about fractions, we are usually talking about proper fractions. A proper fraction is a fraction where the numerator (top number) is less than the denominator (bottom number).

### What is a fraction?

In mathematics, a fraction is a number that represents a part of a whole. It is written with a numerator (a top number) over a denominator (a bottom number). For example, if we have 1/2, we say this is 1 out of 2, or one-half. In fractions, we can only have whole numbers as the numerator and denominator. This means that we cannot have 3 1/2 or 5/4 because those would have 3.5 or 1.25 as the numerator or denominator, and those are not whole numbers.

### What is a proper fraction?

A proper fraction is a fraction where the numerator (top number) is less than the denominator (bottom number). For example, 1/2, 3/4 and 4/5 are all proper fractions.

An improper fraction is a fraction where the numerator is greater than or equal to the denominator. For example, 5/4, 6/5 and 10/8 are all improper fractions.

### What is an improper fraction?

An improper fraction is a fraction in which the numerator (top number) is greater than or equal to the denominator (bottom number).

To convert an improper fraction to a mixed number, follow these steps:

1. Divide the numerator by the denominator. The result will be your whole number.
2. Write down the result as your whole number.
3. Multiply the whole number by the denominator. Subtract this number from the original numerator. This will be your new numerator.
4. Write down your new numerator over the original denominator. This is your mixed number!

## The Basics of 4.5

4.5 can be written as a fraction in a few different ways. The most common way to write 4.5 as a fraction is 9/2. This is because 4.5 can be divided into 9 equal parts, and each of those parts is 1/2.

### What is 4.5 as a decimal?

4.5 as a decimal is 45/10. To get the answer, divide 4 by 5 and move the decimal point two places to the right.

### What is 4.5 as a percent?

4.5% as a decimal is 0.045. In other words, 4.5% is equal to 0.045 per hundred, or 45 out of 10,000. To convert from percentage to decimal, divide by 100. To convert from decimal to percentage, multiply by 100%.

### What is 4.5 as a mixed number?

4.5 as a mixed number is equal to 9/2. To convert a decimal to a mixed number, place the decimal over 1 and multiply by the denominator. The whole number result is the mixed number’s whole part, and the remainder becomes the mixed number’s fractional part.

## Converting 4.5 to a Fraction

You can convert 4.5 to a fraction by first writing it as an improper fraction. An improper fraction is a fraction where the numerator is greater than or equal to the denominator. In this case, 4.5 would be written as 9/2. Therefore, 4.5 as a fraction would be 9/2.

### How to convert 4.5 to a fraction using a calculator
