I = $1,200 * 8/100 * 240/360 =

The correct answer is:

$64.

Explanation:

We will mulitiply the first two numbers first.

We will first write 1200 as a fraction by putting it over 1:
1200/1 * 8/100.
We now multiply straight across: (1200*8)/(1*100) = 9600/100 = 96.

Now we will multiply this by the last fraction. Again we will make the whole number, 96, a fraction by placing it over 1:
(96/1)*(240/360).

Again we multiply straight across: (96*240)/(1*360)=23040/360.

When we divide this out, we get 64.
