David and Wendy share some beads.
38 of David's beads is equal to
313 of Wendy's beads. Given that David has 15 beads less than Wendy, how many beads do they have altogether?
38 of David's beads = 313 of Wendy's beads
Number of David's beads = 8 u
Number of Wendy's beads = 13 u
Number of beads that David has less than Wendy
= 13 u - 8 u
= 5 u
5 u = 15
1 u = 15 ÷ 5 = 3
Total number of beads
= 8 u + 13 u
= 21 u
= 21 x 3
= 63
Answer(s): 63
