Question

find the number by which(-6)-1 should be multiplied so that product becomes 9-1

Answer 1

Hey mate!!

HERE IS THE ANSWER

Let the number be x

${ - 6}^{ - 1} \times x = { 9}^{ - 1} \\ \frac{ - 1}{6} \times x = \frac{1}{9} \\ \frac{ - x}{6} = \frac{1}{9} \\ - x = \frac{1 \times 6}{9} \\ - x = \frac{2}{3} \\ x = \frac{ - 2}{3}$
Hope it helps to you.

Answer 2

Let the no. be x
Then,
-6^-1×x=9^-1
1/-6×x=1/9
x/-6=1/9
x=-6/9
x=-2/3
