Convert 0.4 to a simplified fraction

Answer 1

To convert 0.4 to a simplified fraction, we can write it as a fraction over 1:

0.4 = 0.4/1

Next, we multiply both the numerator and the denominator by 10 to remove the decimal:

0.4/1 * 10/10 = 4/10

Finally, we can simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 2:

4/10 = 2/5

Therefore, 0.4 as a simplified fraction is 2/5.
