Charlie had
16 as many marbles as Jack. Jack had twice as many marbles as Zeph. If Charlie had 74 marbles fewer than Zeph,
- how many marbles did Charlie have?
- how many marbles did they have altogether?
(a)
Number of marbles that Charlie had = 1 u
Number of marbles that Jack had = 6 u
Number of marbles that Zeph had = 6 u ÷ 2 = 3 u
Number of marbles that Charlie had fewer than Zeph
= 3 u - 1 u
= 2 u
2 u = 74
1 u = 74 ÷ 2 = 37
Number of marbles that Charlie had
= 1 u
= 37
(b)
Total number of marbles that they had
= 1 u + 6 u + 3 u
= 10 u
= 10 x 37
= 370
Answer(s): (a) 37; (b) 370
