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