Deb is trying to fit two boxes into the trunk of her car. One box is 7/10 of a foot tall and the other is 7/10 of a foot tall. Stacked on top of each other, what is the combined height of the two boxes?

*Write your answer as a fraction or as a whole or mixed number.*

The height of each box is \( \frac{7}{10} \) feet. To find the combined height of the two boxes when stacked, we add the heights together:

\[
\frac{7}{10} + \frac{7}{10} = \frac{7 + 7}{10} = \frac{14}{10}
\]

The fraction \( \frac{14}{10} \) can be simplified by dividing both the numerator and the denominator by 2:

\[
\frac{14}{10} = \frac{7}{5}
\]

Thus, the combined height of the two boxes is \( \frac{7}{5} \) feet, which is also equal to 1 and \( \frac{2}{5} \) feet as a mixed number.

**Answer: \( 1 \frac{2}{5} \) feet**.
