Fabian had
18 as many marbles as Sam. Sam had twice as many marbles as Flynn. If Fabian had 87 marbles fewer than Flynn,
- how many marbles did Fabian have?
- how many marbles did they have altogether?
(a)
Number of marbles that Fabian had = 1 u
Number of marbles that Sam had = 8 u
Number of marbles that Flynn had = 8 u ÷ 2 = 4 u
Number of marbles that Fabian had fewer than Flynn
= 4 u - 1 u
= 3 u
3 u = 87
1 u = 87 ÷ 3 = 29
Number of marbles that Fabian had
= 1 u
= 29
(b)
Total number of marbles that they had
= 1 u + 8 u + 4 u
= 13 u
= 13 x 29
= 377
Answer(s): (a) 29; (b) 377
