A decimal number can be defined as a number whose whole number part and the fractional part is separated by a decimal point.

Answer: 2/5 as a decimal is 0.4

Let's write 2/5 as a decimal using two methods.

Explanation:

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

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

Here, the fraction is 2/5 which means we need to perform 2 ÷ 5

This gives the answer as 0.4. So, 2/5 as a decimal is 0.4.

Method 2: Writing 2/5 as a decimal by converting the denominator to powers of 10

We will multiply the numerator and denominator with a number to make the denominator a power of 10.

2/5 = (2 × 2) / (5 × 2) = 4/10

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

Decimal moved one place towards left as the denominator was 10. Therefore, 4/10 = 0.4. This means 2/5 as a decimal is 0.4.

Irrespective of the methods used, the answer to 2/5 as a decimal will always remain the same.

You can also verify your answer using Cuemath's Fraction to Decimal Calculator.

Thus, 2/5 as a decimal is 0.4
