Answer:
20%
Step-by-step explanation:
This is a really sad problem but okay
So we are trying to find the success rate which is also known as percentage
To find a percentage we can do
part/whole = percentage/100
So the part would the 9 times the friend landed and the whole would be 45
Now, we have 3 parts of the equation and we can plug them all in to fine x (the success rate)
First you divide the part by the whole and get
9/45 = 0.2
Then you multiply this by 100 to get
A 20% sucess rate
Have a nice day ! <3
