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