Question from tazneem, a student: Is-5/-11 a positive rational number? |
Hi,
If $a, b$ and $c$ are real numbers with $b \ne 0$ and $c \ne 0$ then
\[\frac{a}{b}= \frac{a \times c}{b \times c},\]
in other words they are equivalent fractions. What happens with your fraction $\large \frac{-5}{-11}$ if you take $c = -1?$
