The answer would be -.8
 you can use long division and or see what times 20 equals(obviously it would be a decimal) 
so 20 times .8 = 16    ( 20 times 8 equals 160 but with a decimal, you move it to the left once and you get 16) and one number is negative so the answer will be negative  so -16 divided by 20 equals -.8

hope this helps you :)
