given:
[tex] \frac{1}{15} + \frac{1}{5} + \frac{1}{3} [/tex]
to find:
the simplest form.
solution:
[tex] \frac{1}{15} + \frac{1 \times 3}{5 \times 3} + \frac{1 \times 5}{3 \times 5} [/tex]
[tex] = \frac{1}{15} + \frac{5}{15} + \frac{3}{15} [/tex]
[tex] = \frac{1 + 3 + 5}{15} [/tex]
[tex] = \frac{9}{15} [/tex]
[tex] = \frac{3}{5} [/tex]
therefore, the correct answer is option A.
