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

Answer:

Step-by-step 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:

$\Rightarrow \frac {-1\times 100}{-1\times 2}$

-1 / -1 = 1

Also, 100 / 2 = 50

So,

$\Rightarrow \frac {-1\times 100}{-1\times 2}=50\times 1=50$

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.
