Will has four times as many marbles as Harry. Harry has 12 more marbles than Jeremy. They have a total of 114 marbles.
- How many marbles does Will have?
- How many marbles does Jeremy have?
(a)
Number of marbles that Harry has = 1 u
Number of marbles that Jeremy has = 1 u - 12
Number of marbles that Will has = 4 u
Total number of marbles
= 1 u + 1 u - 12 + 4 u
= 6 u - 12
6 u - 12 = 114
6 u = 114 + 12
6 u = 126
1 u = 126 ÷ 6 = 21
Number of marbles that Will has
= 4 u
= 4 x 21
= 84
(b)
Number of marbles that Jeremy has
= 1 u - 12
= 21 - 12
= 9
Answer(s): (a) 84; (b) 9
