PSLE Luke used
47 of his money to buy 8 files. He used the rest of his money to buy 5 files and 3 staplers.
- What fraction of his money did Luke use to buy the 3 staplers?
- If 1 stapler was given for free for every 4 staplers bought, how many staplers would Luke be able to buy if he were to use all his money to buy staplers?
(a)
Fraction of his money used to buy 5 files and 3 staplers
= 1 -
47 =
37 8 files →
47 of his money
1 pen →
47 ÷ 8 =
114 of his money
5 files → 5 x
114 =
514 of his money
5 files + 3 staplers →
37 of his money
3 staplers →
37 -
514 =
614 -
514 =
114 of his money
(b)
3 staplers →
1141 stapler →
114 ÷ 3 =
142 of his money
If 1 stapler cost
142 of his money, Luke could buy 42 staplers (Not including the free ones).
Number of free staplers that Luke could get
= 42 ÷ 4
= 10 r 2
Total number of staplers that Luke could get
= 42 + 10
= 52
Answer(s): (a)
114; (b) 52
