Ivan and Ben have 19 beads altogether. Ivan has 5 more beads than Ben. Find the number of beads each boy has.
- Ben
- Ivan
Number of beads that Ben has = 1 u
Number of beads that Ivan has = 1 u + 5
Total number of beads
= 1 u + 1 u + 5
= 2 u + 5
2 u + 5 = 19
2 u = 19 - 5 = 14
1 u = 14 ÷ 2 = 7
(a)
Number of beads that Ben has
= 1 u
= 7
(b)
Number of beads that Ivan has
= 1 u + 5
= 7 + 5
= 12
Answer(s): (a) 7; (b) 12
