John and Joelle share some buttons.
23 of John's buttons is equal to
25 of Joelle's buttons. Given that John has 12 buttons less than Joelle, how many buttons do they have altogether?
23 of John's buttons = 25 of Joelle's buttons
Number of John's buttons = 3 u
Number of Joelle's buttons = 5 u
Number of buttons that John has less than Joelle
= 5 u - 3 u
= 2 u
2 u = 12
1 u = 12 ÷ 2 = 6
Total number of buttons
= 3 u + 5 u
= 8 u
= 8 x 6
= 48
Answer(s): 48
