Eric and Caden have 9 balls altogether. Eric has 3 more balls than Caden. Find the number of balls each boy has.
- Caden
- Eric
Number of balls that Caden has = 1 u
Number of balls that Eric has = 1 u + 3
Total number of balls
= 1 u + 1 u + 3
= 2 u + 3
2 u + 3 = 9
2 u = 9 - 3 = 6
1 u = 6 ÷ 2 = 3
(a)
Number of balls that Caden has
= 1 u
= 3
(b)
Number of balls that Eric has
= 1 u + 3
= 3 + 3
= 6
Answer(s): (a) 3; (b) 6
