Answer»

ANSWER:

( \frac{5}{2} \times \frac{ - 16}{5} ) - ( \frac{ - 35}{3} \times \frac{1}{7} \times 21) \\ = (\frac{5 \times - 16 }{2 \times 5} ) - ( \frac{ - 35 \times 1 \times 21}{3 \times 7} ) \\ = ( \frac{ - 16}{2} ) - ( \frac{ - 35 \times 3 \times 7}{3 \times 7}) \\ = ( - 8) - ( - 35) \\ = - 8 + 35 \\ = 35 - 8 \\ = <klux>27</klux>
