Liam had
112 as many marbles as Neave. Neave had twice as many marbles as Owen. If Liam had 120 marbles fewer than Owen,
- how many marbles did Liam have?
- how many marbles did they have altogether?
(a)
Number of marbles that Liam had = 1 u
Number of marbles that Neave had = 12 u
Number of marbles that Owen had = 12 u ÷ 2 = 6 u
Number of marbles that Liam had fewer than Owen
= 6 u - 1 u
= 5 u
5 u = 120
1 u = 120 ÷ 5 = 24
Number of marbles that Liam had
= 1 u
= 24
(b)
Total number of marbles that they had
= 1 u + 12 u + 6 u
= 19 u
= 19 x 24
= 456
Answer(s): (a) 24; (b) 456
