Will and Ahmad have 13 marbles altogether. Will has 3 more marbles than Ahmad. Find the number of marbles each boy has.
- Ahmad
- Will
Number of marbles that Ahmad has = 1 u
Number of marbles that Will has = 1 u + 3
Total number of marbles
= 1 u + 1 u + 3
= 2 u + 3
2 u + 3 = 13
2 u = 13 - 3 = 10
1 u = 10 ÷ 2 = 5
(a)
Number of marbles that Ahmad has
= 1 u
= 5
(b)
Number of marbles that Will has
= 1 u + 3
= 5 + 3
= 8
Answer(s): (a) 5; (b) 8
