8 buttons are to 1 package as ? buttons are to 5 packages.

20
30
40
50

Answer 1

40 buttons are to 5 packages

8/1 = x/5
multiply by 5 on both sides
x=40

Answer 2

8b = 1p (or p) (original statement)
To figure out how to get 5 packages, you multiply each side by 5
8b x 5 = 40b
1p (or p) x 5 = 5p
40b = 5p
So in conclusion, 40b (40 buttons) = 5p (5 packages)
Hope this helped!
