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