At lunch your friend slips a water bottle 45 times and it lands on its base 9 of them. What was their percent of success?

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
