Barry's deck of cards contains 40 blue cards and 60 red cards max's deck of cards contains the same number of blue cards but the ratio blue cards to red cards 5: 9 how many total cards does max's deck of cards contain? need this asap

Max's deck also has 40 blue cards, and for every 5 blue cards in his deck there are 9 red cards. His blue cards can be divided exactly into 8 groups (8 times 5 is 40), so he should also be able to divide his red cards into exactly 8 groups of 9 cards each. So there are 72 red cards in his deck (8 times 9 is 72).
