I am thinking of 2 numbers when i add my numbers the answer is 1 when i multiply my numbers the answer is 0.09 what is the numbers

X + y = 1 ... x = 1 - y

x * y = 0.09

y (1 - y) = 0.09

y - y^2 = 0.09 ... re-arrange

y^2 - y + 0.09 = 0

(y - 0.9) (y - 0.1) = 0

y - 0.9 = 0 x + y = 1

y = 0.9 x + 0.9 = 1

x = 0.1

y - 0.1 x + y = 1

y = 0.1 x + 0.1 = 1

x = 0.9

so ur 2 numbers are : 0.1 and 0.9
