When positive integer A is divided by positive integer B, the result is 4.35. Which of the following could be the remainder when A is divided by B? A/B = 4.35 ---> A = (4.35)*B = 4B + (0.35)*B Hence, when A is divided by B, the remainder is (0.35)*B = 35B/100 = 7B/20 = 7*(B/20) Hence, the remainder...
