Question

Ava used the following equation in order to solve a math problem involving integers.

-h/-k = j

If the equation Ava used is correct, which of the following equations is not correct?

A) - j = -h/k
B) - j = -h/-k
C) - j = h/-k
D) j = h/k

Answer 1

B

Explanation:

Answer 2

The only equation which is incorrect is in option B.

Explanation:

Eva used the following equation in order to solving integers, which is

`(-h)/(-k) = j`

⇒
`j = (h)/(k)` ......... (1)

Now, if the equation Ava used is correct, then we have to find which of the given equations is not correct.

Now, in option A) it is given that
`- j = (- h)/(k)`

⇒
`j = (h)/(k)` which is same as equation (1).

In option B) it is given that
`- j = (- h)/(- k)`

⇒
`j = - (h)/(k)` which is not same as equation (1).

In option C) it is given that
`- j = (h)/(- k)`

⇒
`j = (h)/(k)` which is same as equation (1).

Again, in option D) it is given that
`j = (h)/(k)`

⇒
`j = (h)/(k)` which is same as equation (1).

Therefore, the only equation which is incorrect is in option B. (Answer)
