Answer 2

Answer:

The answer is 56/135

Step-by-step explanation:

The rule of proportionality is

Product of side terms = Product of middle terms

Hence,

$\frac{2}{5} \times \frac{4}{9} = a \times \frac{3}{7}$

or,

$a = \frac{2 \times 4 \times 7}{5 \times 9 \times 3}$

or,

$a = \frac{56}{135}$
