Ahmad and Valen have 19 balls altogether. Ahmad has 3 more balls than Valen. Find the number of balls each boy has.
- Valen
- Ahmad
Number of balls that Valen has = 1 u
Number of balls that Ahmad has = 1 u + 3
Total number of balls
= 1 u + 1 u + 3
= 2 u + 3
2 u + 3 = 19
2 u = 19 - 3 = 16
1 u = 16 ÷ 2 = 8
(a)
Number of balls that Valen has
= 1 u
= 8
(b)
Number of balls that Ahmad has
= 1 u + 3
= 8 + 3
= 11
Answer(s): (a) 8; (b) 11
