Answer 2

Answer:

$\frac{1}{7}$

Step-by-step explanation:

$let \: x \: be \: the \: number \\ \\( { - 7})^{ - 1} \times x = ({ - 49})^{ - 1} \\ \\ \frac{1}{ - 7} \times x = \frac{1}{ - 49} \\ \\ x = \frac{ - 7}{ - 49} \\ \\ x = \frac{1}{7} \\ \\ hence \: \\ \frac{1}{7} \: is \: the \: number \\ \: that \:we \: multiply \: to \: \\ ( { - 7})^{ - 1} to \: get \: ( { - 49})^{ - 1}$
