PSLE Jack used
47 of his money to buy 12 pens. He used the rest of his money to buy 8 pens and 2 markers.
- What fraction of his money did Jack use to buy the 2 markers?
- If 1 marker was given for free for every 4 markers bought, how many markers would Jack be able to buy if he were to use all his money to buy markers?
(a)
Fraction of his money used to buy 8 pens and 2 markers
= 1 -
47 =
37 12 pens →
47 of his money
1 pen →
47 ÷ 12 =
121 of his money
8 pens → 8 x
121 =
821 of his money
8 pens + 2 markers →
37 of his money
2 markers →
37 -
821 =
921 -
821 =
121 of his money
(b)
2 markers →
1211 marker →
121 ÷ 2 =
142 of his money
If 1 marker cost
142 of his money, Jack could buy 42 markers (Not including the free ones).
Number of free markers that Jack could get
= 42 ÷ 4
= 10 r 2
Total number of markers that Jack could get
= 42 + 10
= 52
Answer(s): (a)
121; (b) 52
