What is the value of (8!/6!) ÷ (7!/6!)?

Answer and explanation

Correct answer: 8

Answer: 8, so option C is correct. Simplify each factorial ratio: 8!/6!=8×7 because 8!=8×7×6!, while 7!/6!=7 because 7!=7×6!. The expression therefore becomes (8×7)÷7=8. Another method confirms it: division by a fraction means multiplication by its reciprocal, so (8!/6!)÷(7!/6!)=(8!/6!)×(6!/7!)=8!/7!=8. Option A, 6, leaves the denominator factorial without completing the cancellation; option B, 7, simplifies only the divisor; and option D, 9, has no supporting factorial calculation. Do not cancel symbols across a division sign carelessly. First rewrite the division as multiplication by the reciprocal or simplify each ratio separately.
