Final answer:
In each case (a), (b), and (c), it is not possible to conclude that A = B.
Step-by-step explanation:
(a) No, we cannot conclude that A = B if A × F = B × F. Consider the case where A = 2 and B = 4, and F = 2. A × F = 2 × 2 = 4, and B × F = 4 × 2 = 8, but A does not equal B. Therefore, we cannot make this conclusion.
(b) No, we cannot conclude that A = B if A FB F. This statement is unclear, but assuming it means that A is a factor of B and F, then we can consider the case where A = 2, B = 4, and F = 2. A is a factor of both B and F, but A does not equal B.
(c) No, we cannot conclude that A = B if FÃ = BF. Again, assuming that FÃ means F is a factor of A, consider the case where A = 4, B = 2, and F = 2. 2 is a factor of A, and 2 × 2 = 4, but A does not equal B.
