PSLE Zane used
47 of his money to buy 8 staplers. He used the rest of his money to buy 5 staplers and 4 pencils.
- What fraction of his money did Zane use to buy the 4 pencils?
- If 1 pencil was given for free for every 5 pencils bought, how many pencils would Zane be able to buy if he were to use all his money to buy pencils?
(a)
Fraction of his money used to buy 5 staplers and 4 pencils
= 1 -
47 =
37 8 staplers →
47 of his money
1 pen →
47 ÷ 8 =
114 of his money
5 staplers → 5 x
114 =
514 of his money
5 staplers + 4 pencils →
37 of his money
4 pencils →
37 -
514 =
614 -
514 =
114 of his money
(b)
4 pencils →
1141 pencil →
114 ÷ 4 =
156 of his money
If 1 pencil cost
156 of his money, Zane could buy 56 pencils (Not including the free ones).
Number of free pencils that Zane could get
= 56 ÷ 5
= 11 r 1
Total number of pencils that Zane could get
= 56 + 11
= 67
Answer(s): (a)
114; (b) 67
