Percentage (P) is the number which is usually beside the word "is".
The Percentage is just a part of the base.
If we were to illustrate this in fraction, the numerator would be the percentage while the denominator would be the base.
Say, you got a score of 45/50 in your math test. 45 is the percentage while 50 is the base since the 45 item which you got correct in your test is just a part of the 50 item in your math test.

Base (B) is the number which is usually beside the word "of".
The Base is like the whole number.
If I have 10 books and I have read 6 of it, the base is 10 and the percentage is 6 since the six books that I have read is a part of the ten books I have.

(Examples of Finding R, B, and P):

18 is N% of 24 (Finding Rate, since the number with the percent sign is missing)
117 is 65% of N (Finding base since, the number beside the word "of" is gone)
60% of 880 is what number? (Finding Percentage, since the number beside "is" is missing
