How Can You Express 40% as Both a Decimal and a Simplified Fraction?

Understanding how to convert percentages into decimals and fractions is a fundamental math skill. Let’s look at how we can represent 40% in both formats.

First, to express 40% as a decimal, we divide 40 by 100. This gives:

40%=40/100​=0.40

So, 40% is equivalent to 0.40 as a decimal.

Next, to convert 40% into a simplified fraction, we start with the fraction form 40/100 We simplify this by dividing both the numerator and the denominator by their greatest common divisor, which is 20. This results in:

40/100​ =2/5

​Thus, 40% can also be expressed as the simplified fraction 2/5.
