PSLE Cody used
23 of his money to buy 6 pencils. He used the rest of his money to buy 2 pencils and 3 files.
- What fraction of his money did Cody use to buy the 3 files?
- If 1 file was given for free for every 6 files bought, how many files would Cody be able to buy if he were to use all his money to buy files?
(a)
Fraction of his money used to buy 2 pencils and 3 files
= 1 -
23 =
13 6 pencils →
23 of his money
1 pen →
23 ÷ 6 =
19 of his money
2 pencils → 2 x
19 =
29 of his money
2 pencils + 3 files →
13 of his money
3 files →
13 -
29 =
39 -
29 =
19 of his money
(b)
3 files →
191 file →
19 ÷ 3 =
127 of his money
If 1 file cost
127 of his money, Cody could buy 27 files (Not including the free ones).
Number of free files that Cody could get
= 27 ÷ 6
= 4 r 3
Total number of files that Cody could get
= 27 + 4
= 31
Answer(s): (a)
19; (b) 31
