Question

Solve for x.

1/2x = -9


x = -4 1/2

x = -18

Answer 1

Divide 1/2 to both sides or multiply by its reciprocal, 2.

2 * -9 = ?

Answer 2

-18
-18 / 1/2 right?

Answer 3

Yep, -18 is correct.

Yes, we divide 1/2 or we multiply by the reciprocal of 1/2, and the reciprocal of 1/2 is 2/1 or 2. So we multiplied by 2.

Answer 4

what do u mean?

Answer 5

We never divide fractions.. we multiply them..always.

When we divide like:

3/4 / 6/8 we flip 6/8 and multiply:

3/4 * 8/6

That's what we did here..we don't divide 1/2, we multiply by 2/1 or 2.

Answer 6

so -18*2/1?

Answer 7

No, we multiplied by -9..-18 is our answer :)
