n × four-fifths = three-fourths
A. n = one-half
B. n = fifteen-sixteenths
C. n = 1start fraction 2 over 3 end fraction
To solve for n, we can simplify the left-hand side of the equation by multiplying n and 4/5. Then, we can cross-multiply to solve for n.
n x 4/5 = 3/4
4n/5 = 3/4
4n = 15
n = 15/4 = 3 3/4
Therefore, none of the answer choices A, B, or C are correct. The correct answer is n = 3 3/4.
