Answer:
a, c, d
Step-by-step explanation:
b is NOT equivalent, because the content of parentheses is evaluated first. That makes the expression equal to 2/15, which is not equal to the given expression.
[tex]\dfrac{2}{(5\times 3}=\dfrac{2}{15}\ne\dfrac{2}{5}\times3=\dfrac{6}{5}[/tex]

Expressions (a) and (d) are exactly the same thing, written using different symbols for division. Expression (c) is the equivalent.
