Question

does not understand how -5/12 - 5/6= 5/4

Answer 1

\[\Large -\frac{5}{12}-\frac{5}{6}\]



\[\Large -\frac{5}{12}-\frac{5}{6}\times \frac{2}{2}\]



\[\Large -\frac{5}{12}-\frac{5 \times2}{6 \times 2}\]



\[\Large -\frac{5}{12}-\frac{10}{12}\]



\[\Large \frac{-5-10}{12}\]



\[\Large -\frac{15}{12}\]



\[\Large -\frac{5}{4}\]



So \[\Large -\frac{5}{12}-\frac{5}{6} = -\frac{5}{4}\]
