Julian and Eric have 18 marbles altogether. Julian has 6 more marbles than Eric. Find the number of marbles each boy has.
- Eric
- Julian
Number of marbles that Eric has = 1 u
Number of marbles that Julian has = 1 u + 6
Total number of marbles
= 1 u + 1 u + 6
= 2 u + 6
2 u + 6 = 18
2 u = 18 - 6 = 12
1 u = 12 ÷ 2 = 6
(a)
Number of marbles that Eric has
= 1 u
= 6
(b)
Number of marbles that Julian has
= 1 u + 6
= 6 + 6
= 12
Answer(s): (a) 6; (b) 12
