Rounding it up actually gives a more accurate answer, but doing so without explaining why might confuse @mariposa1415 .

I think that would more correctly answer the question the way it was asked, though there are other ways to estimate.
For example, rounding one number up and rounding the other number down cancels some of the rounding error. If you round all the numbers down then the estimate will necessarily under-represent the actual sum.
