Final answer:
The sum of 1/5, 1/5, and 2/5 is 4/5, therefore the correct answer is E. None of these, as this option is not listed among the choices provided.
Step-by-step explanation:
To calculate the sum 1/5 + 1/5 + 2/5, we add the numerators and keep the denominator the same because all fractions have the same denominator. The calculation is as follows:
1/5 + 1/5 = 2/5 (since 1+1=2)
Now, add 2/5 to the result:
2/5 + 2/5 = 4/5 (since 2+2=4)
Thus, the sum of 1/5, 1/5, and 2/5 is 4/5, which means the correct answer is E. None of these as none of the options provided match the correct answer.
To solve the expression 1/5 + 1/5 + 2/5, we need to add the fractions together. Since the denominators are the same, we can add the numerators and place the sum over the common denominator. In this case, the sum of the numerators is 4, and the common denominator is 5. So the final answer is 4/5.
