Question

Write 0.4 as a fraction or mixed number

Answer 1

the answer of 0.4 is 2/5 or 2 1/5

Answer 2

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 $\frac{4}{10}$. Notice however that the fraction is not in lowest terms. We will need to divide the numerator and the denominator by the greatest common factor of 4 and 10 which is 2. Therefore, 0.4 can be written as the fraction $\frac{2}{5}$, which is in lowest terms.
