1.5 = 3/ = 1 1/ 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/
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/ = (1.5 × 10) = 15/.
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)/ = 3/ 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/ is also equal to 1 1/ when expressed as a mixed number.
