A fraction (from Latin fractus, “broken”) represents a part of a whole or, more generally, any number of equal parts. When spoken in everyday English, a fraction describes how many parts of a certain size there are, for example, one-half, eight-fifths, three-quarters.

## Introduction

In mathematics, a fraction is a number that represents a part of a whole. It is made up of two parts: the numerator and the denominator. The numerator is the number of parts we have, while the denominator is the total number of parts. A proper fraction is one where the numerator is less than the denominator, while an improper fraction is one where the numerator is equal to or greater than the denominator.

When we convert a decimal like -1.5 into a fraction, we are looking for an equivalent fraction where the decimal part (the “.5” in this case) becomes the numerator, and the integer part (the “1” in this case) becomes the denominator. In other words, we want to find a fractions whose decimal part is equal to -0.5 when multiplied by 10.

One way to do this is to multiply both -1.5 and 10 by 2 to get -3 and 20:

-1.5 × 2 = -3

10 × 2 = 20

Then, we can rewrite -1.5 as -3/20:

-1.5 = -3/20

## What is a Fraction?

A fraction is a number that represents a part of a whole. The whole is usually represented by the number 1, and the part is represented by a number less than 1. For example, the fraction 3/4 represents 3 parts out of a total of 4 parts, or 75% of the whole.

## What is -1.5 as a Fraction?

To find an equivalent fraction for -1.5, we find the greatest common factor for 1.5 and 5:

the greatest common factor of 1.5 and 5 is 5, so

-1.5 = (-3)/(5)

## Conclusion

To sum it all up, -1.5 as a fraction is equal to -3/2. This can be simplified to -1 1/2, which is read as “negative one and a half.”
