Answer:
To simplify this expression you want to follow in the order of PEMDAS
First you want to do is the parentheses.
40/ [9.6-(8*0.2)] (first step is 8*0.2)
40/[9.6-1.6] (8*0.2=1.6), ( now you want to do what's in the brackets (also parentheses)
40/8 (9.6-1.6=8) (Last you want to divide)
5 (40/8=5)
5
Hope this helps ;)
