PSLE Mark used
47 of his money to buy 8 files. He used the rest of his money to buy 5 files and 2 staplers.
- What fraction of his money did Mark use to buy the 2 staplers?
- If 1 stapler was given for free for every 5 staplers bought, how many staplers would Mark 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 2 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 + 2 staplers →
37 of his money
2 staplers →
37 -
514 =
614 -
514 =
114 of his money
(b)
2 staplers →
1141 stapler →
114 ÷ 2 =
128 of his money
If 1 stapler cost
128 of his money, Mark could buy 28 staplers (Not including the free ones).
Number of free staplers that Mark could get
= 28 ÷ 5
= 5 r 3
Total number of staplers that Mark could get
= 28 + 5
= 33
Answer(s): (a)
114; (b) 33
