Vincent had
16 as many marbles as Jeremy. Jeremy had twice as many marbles as Jenson. If Vincent had 82 marbles fewer than Jenson,
- how many marbles did Vincent have?
- how many marbles did they have altogether?
(a)
Number of marbles that Vincent had = 1 u
Number of marbles that Jeremy had = 6 u
Number of marbles that Jenson had = 6 u ÷ 2 = 3 u
Number of marbles that Vincent had fewer than Jenson
= 3 u - 1 u
= 2 u
2 u = 82
1 u = 82 ÷ 2 = 41
Number of marbles that Vincent had
= 1 u
= 41
(b)
Total number of marbles that they had
= 1 u + 6 u + 3 u
= 10 u
= 10 x 41
= 410
Answer(s): (a) 41; (b) 410
