Answer 2

Hey mate !!

Here's your answer !!

Multiply 10 to both the numbers:

$\frac{ - 2}{1} \times \frac{10}{10} \: \: and \: \: \frac{ - 1}{1} \times \frac{10}{10}$

$\frac{ - 20}{10} \: \: and \: \: \frac{ - 10}{10}$

$so \: the \: numbers \: are \: \\ \\ = \: \frac{ - 11}{10} \: \: \frac{ - 12}{10} \: \: \frac{ - 13}{10} \: ..... \: \: \frac{ - 19}{10} \\ \\ any \: three \: numbers \: can \: be \: taken.$

Hope it helps !!
