To express 1.5 as a fraction, we can follow a few simple steps:
- 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.
- Next, convert the decimal 0.5 into a fraction. The decimal 0.5 is the same as 1/2.
- Now we can rewrite 1.5 as:
- 1.5 = 1 + 0.5 = 1 + 1/2
- 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.
- Now we need a common denominator to add 1/1 and 1/2. The least common denominator (LCD) of 1 and 2 is 2.
- Convert 1/1 to have this common denominator:
- 1/1 = 2/2
- 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.
