We can rewrite this as

$\frac{3}{8}$ divided by ($\frac{3}{4}$ -$\frac{1}{3}$) divided by $\frac{2}{5}$

simplifying the middle term by evaluating the subtraction

$(\frac{3}{4} - \frac{1}{3}) = \frac{9-4}{12} = \frac{5}{12}$

Thus, the division can be rewritten as

$\frac{3}{8}$ divided by $\frac{5}{12}$ divided by $\frac{2}{5}$

As per PEMDAS or BODMAS, we move from left to right and perform the division.

We can divide the first term by the subsequent terms or

we can also multiply the first term with the reciprocal of the subsequent terms turning

$\frac{3}{8}$ divided by $\frac{5}{12}$ divided by $\frac{2}{5}$ into

$\frac{3}{8} \times \frac{12}{5} \times \frac{5}{2}$

$= \frac{9}{4} = 2.25$

The correct answer is Choice A
