Question

Solve for x: `1000x=436.36`?

Answer 1

`x=0.43636`

Explanation:

`1000x=436.36`

`x=436.36/1000`

`x=0.43636`

Answer 2

`0.43636`

Explanation:

Let's divide both sides by `1000` to isolate `x`. We get

`x=436.36/1000`

Dividing by `1000` is the same as looping the decimal three places to the left. Doing this, we will get

`0.43636`

Note that dividing by `1000` is the same as multiplying by `10^(-3)`, which would give us

`436.36*10^(-3)`, or `4.3636*10^(-1)`

Hope this helps!
