Billy and Yoko share some cards.
78 of Billy's cards is equal to
715 of Yoko's cards. Given that Billy has 14 cards less than Yoko, how many cards do they have altogether?
78 of Billy's cards = 715 of Yoko's cards
Number of Billy's cards = 8 u
Number of Yoko's cards = 15 u
Number of cards that Billy has less than Yoko
= 15 u - 8 u
= 7 u
7 u = 14
1 u = 14 ÷ 7 = 2
Total number of cards
= 8 u + 15 u
= 23 u
= 23 x 2
= 46
Answer(s): 46
