________ in 10 drug users work full time.

Explanation:
Interpreting proportions expressed as “in 10” is a common way to convey prevalence. If seven in ten work full time, that means 7 out of 10 people, which is 7/10 = 0.7, or 70%. So the expression asks for the number that corresponds to 70% of 10, which is seven. The other options would represent 10% (one), 30% (three), and 50% (five), which do not match the 70% described.
