The answer to the question is D. The sum of two irrational numbers cannot be rational. For example, pi plus pi is not going to be a rational number. The product of a rational and irrational number is not always rational. For example, if you multiply 6/5 and pi, you will not get a rational number. The sum of two rational numbers also cannot be irrational, because the original numbers are rational. This leaves only D available. Hope this helps!

Notice that the denominators are 3 and 7, which are factors of 21.

So express all the fractions with denominator 21:

On Monday $\frac{1}{7} = \frac{1}{7} * \frac{3}{3} = \frac{3}{21}$ are sold
On Tuesday $\frac{1}{3} = \frac{1}{3} * \frac{7}{7} = \frac{7}{21}$ are sold
On Wednesday $\frac{2}{7} = \frac{2}{7} * \frac{3}{3} = \frac{6}{21}$ are sold

by Thursday $\frac{3}{21}+\frac{7}{21}+\frac{6}{21} = \frac{3+7+6}{21}= \frac{16}{21}$ of the tickets was sold.

Answer: $\frac{16}{21}$
