Question: 48

Page: 158

Difficulty: 600

\(1-(\frac{1}{2}-\frac{2}{3})=1-\frac{1}{2}+\frac{2}{3}=\frac{1}{2}+\frac{2}{3}\)

The result must be greater than \(1\), so we have to choose between A and B.

Since we have two fractions with \(2\) and \(3\) in the denominator, the final result should be an improper fraction with \(6\) in the denominator.

Hence, answer B.

NB: Even without a calculator on the test, I don't think it would be a problem for anybody. I would say a below 500 level question.

I am just trying to find any type of shortcut for such questions, taking advantage of the multiple choices...really boring to simply add/subtract fractions...
