Question

if demontra divided negative 100 by negative 2 and got negative 200 did why was the answer wrong and was anything done right?

Answer 1

Explanation:

Demontra has to divide negative 100 by negative 2, which means she has to do:

`\Rightarrow \frac {-100}{-2}`

This can be written as:

`\Rightarrow \frac {-1* 100}{-1* 2}`

-1 / -1 = 1

Also, 100 / 2 = 50

So,

`\Rightarrow \frac {-1* 100}{-1* 2}=50* 1=50`

She got -200 which is wrong as she muliplied the numbers which is also wrong as -100 × -2 = 200

She did not done anything right.
