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.
