PSLE Bryan used
47 of his money to buy 12 notebooks. He used the rest of his money to buy 8 notebooks and 3 staplers.
- What fraction of his money did Bryan use to buy the 3 staplers?
- If 1 stapler was given for free for every 6 staplers bought, how many staplers would Bryan be able to buy if he were to use all his money to buy staplers?
(a)
Fraction of his money used to buy 8 notebooks and 3 staplers
= 1 -
47 =
37 12 notebooks →
47 of his money
1 pen →
47 ÷ 12 =
121 of his money
8 notebooks → 8 x
121 =
821 of his money
8 notebooks + 3 staplers →
37 of his money
3 staplers →
37 -
821 =
921 -
821 =
121 of his money
(b)
3 staplers →
1211 stapler →
121 ÷ 3 =
163 of his money
If 1 stapler cost
163 of his money, Bryan could buy 63 staplers (Not including the free ones).
Number of free staplers that Bryan could get
= 63 ÷ 6
= 10 r 3
Total number of staplers that Bryan could get
= 63 + 10
= 73
Answer(s): (a)
121; (b) 73
