Step-by-step explanation:
The percentage 12% can be written as the decimal value 0.12. In this context, "of" is equivalent to "times", so your expression ...
12 percent of 5
is equivalent to
0.12 × 5
which can also be written as ...
(0.12)(5) . . . . . . matches the first choice
_____
Additional comments
The commutative property is a property of multiplication, so this product can be rearranged several ways.
(0.12)(5) = (12/100)(5) = (12)(1/100)(5) = (12)(5/100) = (12)(0.05)
You will notice this last arrangement matches the 3rd choice. In other words, that expression, too, would find 12% of 5. You can also check this one, if this is a "check all that apply" question.

Essentially the % sign and /100 are interchangeable. That is 12% = 12/100. This fraction is pronounced "twelve hundredths", as is the decimal fraction 0.12.
