1.5 in fraction form is 3/2. To convert a decimal like 1.5 to a fraction, follow these steps:
1. Write down the decimal divided by 1: 1.5/1.
2. Multiply both the numerator and the denominator by 10 for every digit after the decimal point. Since 1.5 has one digit after the decimal, multiply by 10: (1.5 × 10)/(1 × 10) = 15/10.
3. Simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor (GCD). The GCD of 15 and 10 is 5, so divide both by 5: (15 ÷ 5)/(10 ÷ 5) = 3/2.
So, 1.5 in fraction form is 3/2.
