Answer 2

Answer: 2/5

Step-by-step explanation: Using the place value chart we can see that the decimal 0.4 is four-tenths, so we can write 0.4 as the fraction 4/10. Notice however that 4/10 is not in lowest terms so we need to divide the numerator and denominator by the greatest common factor of 4 and 10 which is 2. If we divide the numerator and the denominator by 2, we get the equivalent fraction 2/5. Therefore, 0.4 can be written as the fraction 2/5
