Answer: 0.40
Step-by-step explanation: To write 2/5 as a decimal, we need to find a fraction that is equivalent to 2/5 that has a 100 in the denominator. Notice that if we multiply both the numerator and denominator of 2/5 by 20, we get the equivalent fraction 40/100 which we can no write as a decimal. Remember that the hundredths place is two places to the right of the decimal point so we can write 40/100 as 0.40. Therefore, 2/5 is equivalent to 0.40.
