let a and b are the two numbers. then it will be ab=0.2 (1) and a/b=0.8 (2) from the (2) we get
a=0.8b plugging this value of a to the (1) we get 0.8bb=0.2 or 0.8b2=0.2 ====> b2=0.2/0.8 so
b2=1/4 and b=sqrt (1/4) = +/-1/2 the negative value is rejected. plugging this value of b to (2)
we get a/(1/2)=0.8 ----->>> 2a=0.8 so a=0.8/2=0.4 so a=0.4 and b=1/2 are the two numbers we re
looking for. so ab=0.4(1/2)=0.2 and a/b=0.4/(1/2)=0.8
