A company manufactured two items last week: 100 engines and 96 lawn mowers. It was discovered that 15 engines and 3 lawn mowers were defective. Of the engines that were not defective, 45 were of the highest quality, and 40 were not of the highest quality of the lawn mowers that were not defective, 52 were of the highest
quality, and 41 were not of the highest quality
(a) What fractional part of all items manufactured was of the highest quality?
(b) What fractional part of all items manufactured was defective?
