PSLE Lee used
59 of his money to buy 10 notebooks. He used the rest of his money to buy 7 notebooks and 3 staplers.
- What fraction of his money did Lee use to buy the 3 staplers?
- If 1 stapler was given for free for every 5 staplers bought, how many staplers would Lee be able to buy if he were to use all his money to buy staplers?
(a)
Fraction of his money used to buy 7 notebooks and 3 staplers
= 1 -
59 =
49 10 notebooks →
59 of his money
1 pen →
59 ÷ 10 =
118 of his money
7 notebooks → 7 x
118 =
718 of his money
7 notebooks + 3 staplers →
49 of his money
3 staplers →
49 -
718 =
818 -
718 =
118 of his money
(b)
3 staplers →
1181 stapler →
118 ÷ 3 =
154 of his money
If 1 stapler cost
154 of his money, Lee could buy 54 staplers (Not including the free ones).
Number of free staplers that Lee could get
= 54 ÷ 5
= 10 r 4
Total number of staplers that Lee could get
= 54 + 10
= 64
Answer(s): (a)
118; (b) 64
