13/15 is the right answer. First you had to add by the fractions. And it gave us, [tex]\frac{3}{15}+ \frac{10}{15}[/tex]. Since the denominator are equal, and then combine by the fraction. And it gave us, [tex]\frac{3+10}{15}[/tex]. Finally, add the numbers and it gave us the answer is 13/15 is the right answer. Hope this helps! And thank you for posting your question at here on brainly, and have a great day. -Charlie
