What is 1.5 as a fraction?

Fractions form an integral part of Mathematics. A fraction is a part of any quantity out of a whole, where, the whole can be any number, a specific value, or a thing. Whereas, a decimal number can be defined as a number in which the whole number part and the fractional part are separated by a decimal point. Let us understand how to express the decimal 1.5 as a fraction in simplest form and learn the method to convert 1.5 in fraction form.

Answer: 1.5 as a fraction is written as 3/2

Let us see how to convert 1.5 as a fraction in simplest form.

1.5 as a Fraction in Simplest Form

Explanation:

In order to express 1.5 simplified as a fraction, let us use the following steps.

Step 1: Write the given number as the numerator and place 1 in the denominator right below the decimal point followed by the number of zeros required accordingly. Then, this fraction can be simplified.

In this case, 1.5 has one number after the decimal, so, we place 10 in the denominator and remove the decimal point. This will make it 15/10

Step 2: Now, let us see how 15 over 10 is expressed. We can see that 15/10 is not in the simplified form. We know that the HCF (Highest Common Factor) of 15,10 = 5. So, this fraction can be simplified as follows.

After reducing this fraction we get,

⇒ (15 ÷ 5) / (10 ÷ 5) = 3/2

15/10 = 3/2

Therefore, we reduced the fraction 15/10 to 3/2. In other words, when we convert 1.5 into a fraction, we get 3/2.

1.5 as a Mixed Fraction

When we convert 1.5 to a fraction in the simplest form, we first get an improper fraction, 3/2. In order to express 1.5 as a mixed fraction, we can convert 3/2 to a mixed fraction which will be 1\(\dfrac{1}{2}\)
