Help me pls (picture below)

The answer should be 3/2. if x/y = 2/3 then it should be assumed x is equal to 2 and y is equal to 3, therefore if you flip it then you simply flip 2/3 into 3/2 and arrive at the answer.

can someone please do this for me and tell me how so I can do the other one pleaseeee I don't know what to do
KonstantinChe [14]

Answer:

P(green) =1/4

P(orange)=1/2

Step-by-step explanation:

I'm assuming this is probability but it\s been a while, so i'm not sure

number one is a square being divided into half and then one half is being divided into quarters. (as shown by the dotted lines and right angle)

so the probablity of landing in green is 1/4, because it is one fourth of the square.

the probability of the orange is 1/2 because it is 1/2 of the square

The same logic would apply to the "circle" i can see in the next problem. 120 degrees is 1/3 of 360, 90 is 1/4, and so on.

Hope that helps.
