Negative one over two equals negative five over eighteen h

the answer is h = 5 / 9.

Step-by-step explanation:

Given is "negative one over two equals negative five over eighteen h"

It means -1 / 2 = -5 / 18h

Using cross multiplication method,

-1 * 18h = -5 * 2

-18h = -10

Cancelling negative signs from both sides,

18h = 10

Dividing both sides by 18,

h = 10 / 18

h = 5/ 9

Hence, the answer is h = 5 / 9.

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
