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