PSLE Will used
47 of his money to buy 8 notebooks. He used the rest of his money to buy 5 notebooks and 3 files.
- What fraction of his money did Will use to buy the 3 files?
- If 1 file was given for free for every 5 files bought, how many files would Will be able to buy if he were to use all his money to buy files?
(a)
Fraction of his money used to buy 5 notebooks and 3 files
= 1 -
47 =
37 8 notebooks →
47 of his money
1 pen →
47 ÷ 8 =
114 of his money
5 notebooks → 5 x
114 =
514 of his money
5 notebooks + 3 files →
37 of his money
3 files →
37 -
514 =
614 -
514 =
114 of his money
(b)
3 files →
1141 file →
114 ÷ 3 =
142 of his money
If 1 file cost
142 of his money, Will could buy 42 files (Not including the free ones).
Number of free files that Will could get
= 42 ÷ 5
= 8 r 2
Total number of files that Will could get
= 42 + 8
= 50
Answer(s): (a)
114; (b) 50
