Answer 1

Answer:

20.25

Step-by-step explanation:

$(\frac{5}{7} \times \frac{28}{15} \times \frac{9}{8} \times 3) \times \frac{9}{2}$

$= ( \frac{140}{105} \times \frac{27}{8} ) \times \frac{9}{2}$

$= ( \frac{3780}{840} ) \times \frac{9}{2}$

$= \frac{378}{84} \times \frac{9}{2}$

$= \frac{3402}{168}$

$= 20.25$
