1.5 in fraction form is 3/2.
To convert a decimal number x to a fraction, we use the following steps.
- Move the decimal in x to the end of the number to create a new number, call it y. This will be the numerator of your fraction.
- Count how many places you moved the decimal and call it n. 10n will be the denominator of your fraction.
- Write x in fraction form as y / 10n.
- Simplify the fraction.
Let's take 1.5 through these steps.
- Move the decimal in 1.5 to the end of the number to get 15. This is our numerator.
- Count the number of places we moved the decimal. In this case, we moved the decimal one place to get it to the end of 1.5, so 101 will be our denominator.
- Write 1.5 in fraction form as 15/101.
- Lastly, we simplify 15/101.
- 15/101
- Simplify the denominator:
- Simplify the fraction 15/10:
- 15/10 = (5 × 3) / (5 × 2) = 3/2
We get that 1.5 in fraction form is 3/2.
