Julian and Ivan have 18 marbles altogether. Julian has 8 more marbles than Ivan. Find the number of marbles each boy has.
- Ivan
- Julian
Number of marbles that Ivan has = 1 u
Number of marbles that Julian has = 1 u + 8
Total number of marbles
= 1 u + 1 u + 8
= 2 u + 8
2 u + 8 = 18
2 u = 18 - 8 = 10
1 u = 10 ÷ 2 = 5
(a)
Number of marbles that Ivan has
= 1 u
= 5
(b)
Number of marbles that Julian has
= 1 u + 8
= 5 + 8
= 13
Answer(s): (a) 5; (b) 13
