Four twenties equal 80 (since 4 x 20 = 80). To find out how many fives are in 80, you divide 80 by 5, which equals 16. Therefore, there are 16 fives in four twenties.
There are four fives and four nines; so the number of cards that are a five or a nine is 4 + 4 or 8.

Nine fives is 45. As a mixed number that is 450/k where k is ANY non-zero number.
Four fives do not equal 18 - they equal 20.
no
They don't
It's impossible.
No, because 5 x 4 = 20
50 + 50 + 50 + 5 = 8
55 + 5/5 = 56
