when pam saves 2, brother saves 5
so if Pam has 40
40/2 (the number of dollars Pam saves) = 20
20 x 5 = 100 ( the number of dollars her bro saves)
her bro has 100 dollars
hope this helps
basically divide 2 from 40 and then multiply the answer with 5, and you get the number of money her bro saves
hope this helps
