Luis had
110 as many marbles as Jenson. Jenson had twice as many marbles as Charlie. If Luis had 116 marbles fewer than Charlie,
- how many marbles did Luis have?
- how many marbles did they have altogether?
(a)
Number of marbles that Luis had = 1 u
Number of marbles that Jenson had = 10 u
Number of marbles that Charlie had = 10 u ÷ 2 = 5 u
Number of marbles that Luis had fewer than Charlie
= 5 u - 1 u
= 4 u
4 u = 116
1 u = 116 ÷ 4 = 29
Number of marbles that Luis had
= 1 u
= 29
(b)
Total number of marbles that they had
= 1 u + 10 u + 5 u
= 16 u
= 16 x 29
= 464
Answer(s): (a) 29; (b) 464
