Question

the sum of two decimal is 0.9 and their product is 0.18.the two decimal are ​

Answer 1

0.3 and 0.6 is the ans.

let x and y be two decimals.

their sum is 0.9

x + y = 0.9

their product is 0.18

x × y = 0.18

y = 0.18/x

substituting value of y in above 1st eqn

x + 0.18/x = 0.9

x2 + 0.18 = 0.9x

x2 - 0.9x + 0.18= 0

x2 -0.6 x - 0.3x +0.18 =0

x(x-0.6) - 0.3(x-0.6) =0

(×-0.6) (x-0.3) =0

x-0.6=0 0r x - 0.3 =0

x= 0.6 0r x= 0.3

Hence ur ans is two decimals will be 0.6 and 0.3

Answer 2

Answer:

1st no is 0.6

2nd no iz 0.3

Step-by-step explanation:

x+x=0.9 2x =0.9 x= 0.9-0.3 =0.6

x×x=0.18 x²= 0.18 x =0.18-0.15
