Here are four expressions that have the value \(\frac {\text{-}1}{2}\):
\(\frac {\text{-}1}{4} + \left(\frac {\text{-}1}{4}\right)\)
\(\frac12 - 1\)
\(\text-2 \boldcdot \frac14\)
\(\text-1 \div 2\)
Write five expressions: a sum, a difference, a product, a quotient, and one that involves at least two operations that have the value \(\frac {\text{-}3}{4}\).
