Tamara and Amir shared a candy bar. Tamara ate two fifths. Amir ate two fifths. How much is left?
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}}.
To find out how much is left, we need to subtract the amount that Tamara and Amir ate from the original candy bar.
First, let's calculate how much Tamara ate:
If we represent the whole candy bar as 1, Tamara ate 2/5 of it.
So, the amount Tamara ate is:
2/5 * 1 = 2/5
Now let's calculate how much Amir ate:
Just like Tamara, Amir also ate 2/5 of the candy bar.
So, the amount Amir ate is:
2/5 * 1 = 2/5
To calculate how much is left, we need to subtract the sum of what Tamara and Amir ate from the original candy bar:
1 - (2/5 + 2/5) = 1 - 4/5 = 1/5
Therefore, there is 1/5 of the candy bar left.
