• A.

  \(\Large \dfrac{7}{10}\)

• B.

  \(\Large 7\)

• C.

  \(\Large 10\)

• D.

  \(\Large \dfrac{10}{7}\)

   \(\Large 3 \times \dfrac{7}{10} + \dfrac{7}{10} \times 5 + 2 \times \dfrac{7}{10}\)

= \(\Large (3 + 5 + 2) \times \dfrac{7}{10}\)

= \(\Large 10 \times \dfrac{7}{10}\)

= \(\Large 7\)
