Answer 2

Answer:

$\dfrac{4}{5}$

Step-by-step explanation:

Given Problem:

By what number should (-8)-1 be multiplied so that the product equal to (-10)-1?

Solution:

To Find:

The number that should (-8)-1 be multiplied so that the product equal to (-10)-1?

Method:

Let the unknown number will be x

$\implies\ (-8)^-^1 \times\ x =(10)^-^1$

$\implies\dfrac{-1}{8} \times\ x = \dfrac{-1}{10}$

$\implies\ Now, Reciprocal\ of \ these \ fractions.$

$\implies\ x = \dfrac{-1}{10} \times\ \dfrac{8}{-1}$

$\implies\ x = \dfrac{8}{10}$

$\implies\ x = \dfrac{4}{5} \ (Divide \ on \ the \ table \ of \ 2)$
