How can I express 1.5 as a fraction?

To express 1.5 as a fraction, we can follow a few simple steps:

1. First, recognize that 1.5 can be broken down into a whole number and a decimal. We can express 1.5 as 1 + 0.5.
2. Next, convert the decimal 0.5 into a fraction. The decimal 0.5 is the same as 1/2.
3. Now we can rewrite 1.5 as:
• 1.5 = 1 + 0.5 = 1 + 1/2
4. To combine the whole number and the fraction, convert the whole number 1 into a fraction. Remember, any whole number can be written as itself over 1. Therefore, 1 = 1/1.
5. Now we need a common denominator to add 1/1 and 1/2. The least common denominator (LCD) of 1 and 2 is 2.
6. Convert 1/1 to have this common denominator:
• 1/1 = 2/2
7. Now, we can add:
• 2/2 + 1/2 = 3/2

Therefore, 1.5 as a fraction is 3/2. If you want to express it as a mixed number, it would be 1 1/2.

In conclusion, the decimal 1.5 can be represented as both 3/2 in fractional form and 1 1/2 as a mixed number.
