What fraction of an 80-member faculty remains after 20 teachers are reassigned?
Show answer Hide answer
Answer: D. 75
Explanation
Starting faculty count equals eighty members before any reassignment actions occur. Reassigning twenty teachers leaves sixty faculty members remaining at the institution. The remaining count equals sixty teachers out of the original eighty total. Basic subtraction determines remaining quantities after elements are removed from sets. Faculty counts represent the total number of active teaching staff members. Word problems distinguish between fractional proportions and absolute remaining counts.
School administrators track staffing levels after teacher transfers and reassignments. Human resources departments monitor active employee headcounts across departments. Educational planners evaluate faculty student ratios following staff adjustments. Option A represents an incorrect small number unrelated to the faculty subtraction. Option B matches the number of reassigned teachers rather than the remaining count. Option C equals the exact number of remaining teachers but matches a different numbering.
