Propagating error

Find the absolute and percent relative error for each calc.
b) 81.5 (+/ 0.5) x 40.2 (+/ 0.2)/ 21.8 (+/ 0.2)
my answer for absolute error was 150. +/ 200, which is outrageous. Can someone show how they would do it so I can compare and find my mistake?
error/(81.5* 40.2/ 21.8)=.5/81.5 +0.2/40.2 + .2/21.8
absolute error = about 3, so the percent error would be 3/(81.5* 40.2/ 21.8) *100 or 300/150 about 2 percent.
check you work.
