In each of the following cases, write the rational number whose numerator and denominator are respectively as under:
(a) 5–39 and 54–6
(b) (-4)×6 and 8÷2
(c) 35÷(-7) and 35–18
(d) 25+15 and 81÷40
(a) -34/48
(b) -24/4
(c) -5/17
(d) 1600/81
Evaluate numerator and denominator expressions separately then form \(p/q\).
