PSLE Neave used
59 of his money to buy 10 markers. He used the rest of his money to buy 7 markers and 3 pencils.
- What fraction of his money did Neave use to buy the 3 pencils?
- If 1 pencil was given for free for every 4 pencils bought, how many pencils would Neave be able to buy if he were to use all his money to buy pencils?
(a)
Fraction of his money used to buy 7 markers and 3 pencils
= 1 -
59 =
49 10 markers →
59 of his money
1 pen →
59 ÷ 10 =
118 of his money
7 markers → 7 x
118 =
718 of his money
7 markers + 3 pencils →
49 of his money
3 pencils →
49 -
718 =
818 -
718 =
118 of his money
(b)
3 pencils →
1181 pencil →
118 ÷ 3 =
154 of his money
If 1 pencil cost
154 of his money, Neave could buy 54 pencils (Not including the free ones).
Number of free pencils that Neave could get
= 54 ÷ 4
= 13 r 2
Total number of pencils that Neave could get
= 54 + 13
= 67
Answer(s): (a)
118; (b) 67
