Answer: 1 in 18
This is the same as writing the fraction 1/18
==============================================================
Explanation:
Since she has 36 marbles total, and the probability of picking green is 1 in 2, this means (1/2)*36 = 18 marbles are green.
Then she also has (1/3)*36 = 12 red marbles and (1/9)*36 = 4 blue marbles.
So far, that accounts for 18+12+4 = 34 marbles in all. That leaves 36-4 = 2 marbles left over that must be black, as it's the only color left.
From that, the probability of choosing a black marble is 2/36 = 1/18.
There's a 1 in 18 chance of Maddy picking a black marble.
1/18 = 0.0556 = 5.56% approximately

Answer:
The cost of parking the car for 1 hour = $2.5
Step-by-step explanation:
Cost of parking car for two hours = $5
Now, let the cost of parking the car for one hour be $x
Since, the car is parked for two hours and the cost charged is $5
So, each hour the cost of parking is same ⇒ Cost of parking one hour is half the cost of parking the car for two hours.
Since, the cost of parking the car for one hour = $x
So, cost of parking the car for two hours = 2x
But this cost is given to be $5
⇒ 2x = 5
⇒ x = 2.5
Hence, The cost of parking the car for 1 hour = $2.5
A:b = 8:5 b:c = 3:4
since both sides have b. make b the same. multiply the left by the right side b value of 3 and multiply the right by the left side b value of 5.
3(a:b) and 5(b:c)
3 (8:5) and 5(3:4)
24:15 15:20
now that both sides have the same b value
a:b:c = 24:15:20
