1.5 as a fraction


1.5 = 3/2 = 1 1/2 as a fraction

To convert the decimal 1.5 to a fraction, just follow these steps:

Step 1: Write down the number as a fraction of one:

1.5 = 1.5/1

Step 2: Multiply both top and bottom by 10 for every number after the decimal point:

As we have 1 numbers after the decimal point, we multiply both numerator and denominator by 10. So,

1.5/1 = (1.5 × 10)/(1 × 10) = 15/10.

Step 3: Simplify (or reduce) the above fraction by dividing both numerator and denominator by the GCD (Greatest Common Divisor) between them. In this case, GCD (15,10) = 5.

So, (15÷5)/(10÷5) = 3/2 when reduced to the simplest form.

As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 15/10 is also equal to 1 1/2 when expressed as a mixed number.
