So for this you need to find 15% of 60. There are a few ways to do this but I prefer to do it like this.
First, find 10% of 60. This can be found by dividing 60 by 10, because 100%/10% is 10.
This gives 10%=6
5% is half of 10%, so divide your answer for 10% (6), by 2.
This gives 5%=3
We needed 15%, so we add our 10% and 5% together, to get 9.
15% of 60 is 9, meaning there are 9 puppies.
Hope this helps!
Its 18....................................
The starting percent is 100%. After one hour, bacteria tripled, so it is 300%.
