Ethan had 216 beads more than Opal. Given that they have a total of 412 beads,
- how many beads did Opal have?
- how many beads did Ethan have?
(a)
Number of beads that Ethan that = 1 u + 216
Number of beads that Opal had = 1 u
Total number of beads
= 1 u + 216 + 1 u
= 2 u + 216
2 u + 216 = 412
2 u = 412 - 216
2 u = 196
1 u = 196 ÷ 2 = 98
Number of beads that Opal had
= 1 u
= 98
(b)
Number of beads that Ethan had
= 1 u + 216
= 98 + 216
= 314
Answer(s): (a) 98; (b) 314
