Julian had
112 as many marbles as Wesley. Wesley had twice as many marbles as Zeph. If Julian had 100 marbles fewer than Zeph,
- how many marbles did Julian have?
- how many marbles did they have altogether?
(a)
Number of marbles that Julian had = 1 u
Number of marbles that Wesley had = 12 u
Number of marbles that Zeph had = 12 u ÷ 2 = 6 u
Number of marbles that Julian had fewer than Zeph
= 6 u - 1 u
= 5 u
5 u = 100
1 u = 100 ÷ 5 = 20
Number of marbles that Julian had
= 1 u
= 20
(b)
Total number of marbles that they had
= 1 u + 12 u + 6 u
= 19 u
= 19 x 20
= 380
Answer(s): (a) 20; (b) 380
