Question

Find four rational numbers equivalent to the following.
$-1$

Answer 1

$-1$ can also be written as $\frac{-1}{1}$

To find equivalent rational number, we have to multiply and divide numerator with same number except $0$

$\therefore \frac{-1}{1}=\frac{-1\times 2}{1\times 2}=\frac{-2}{2}$

$\therefore \frac{-1}{1}=\frac{-1\times 3}{1\times 3}=\frac{-3}{3}$

$\therefore \frac{-1}{1}=\frac{-1\times 4}{1\times 4}=\frac{-4}{4}$

$\therefore \frac{-1}{1}=\frac{-1\times 5}{1\times 5}=\frac{-5}{5}$

So, equivalent numbers of $-1$ are$\frac{-2}{2},$ $\frac{-3}{3},\frac{-4}{4},\frac{-5}{5}$
