Tamara and Amir shared a candy bar. Tamara ate two fifths. Amir ate two fifths. How much is left?

1 answer

Tamara and Amir each ate two fifths of the candy bar, so they ate a total of 2/5 + 2/5 = 4/5 of the candy bar.
This means there is 1 - 4/5 = 1/5 of the candy bar left. Answer: \boxed{\frac{1}{5}}.
