To find:

Decimal form of 5/2?

Solution:

Let's see how 5/2 can be written as a decimal using two methods.

Method 1: Writing 5/2 as a decimal using division method:

To transform any fraction to decimal form, we need to divide its numerator by denominator.

Here, the fraction is 5/2 which indicates we have to solve it as 5÷2

     

The answer thus is 2.5. So, 5/2 as a decimal is 2.5

Method 2: We can also write 5/2 as a decimal by transforming the denominator to powers of 10

Multiply the numerator and denominator with a number to make the denominator a power of 10.

5/2= (5× 5) / (2× 5) = 25/10

Now, move the decimal towards left as the number of zeroes are there in the denominator which is a power of 10.

Decimal  will move one place towards left as the denominator was 10 i.e only one zero

Therefore, 25/10 = 2.5. This means 5/2 as a decimal is 2.5.

Using any method, the answer to 5/2 as a decimal will always remain the same.
