PSLE Cody used
35 of his money to buy 6 files. He used the rest of his money to buy 3 files and 2 pencils.
- What fraction of his money did Cody use to buy the 2 pencils?
- If 1 pencil was given for free for every 6 pencils bought, how many pencils would Cody be able to buy if he were to use all his money to buy pencils?
(a)
Fraction of his money used to buy 3 files and 2 pencils
= 1 -
35 =
25 6 files →
35 of his money
1 pen →
35 ÷ 6 =
110 of his money
3 files → 3 x
110 =
310 of his money
3 files + 2 pencils →
25 of his money
2 pencils →
25 -
310 =
410 -
310 =
110 of his money
(b)
2 pencils →
1101 pencil →
110 ÷ 2 =
120 of his money
If 1 pencil cost
120 of his money, Cody could buy 20 pencils (Not including the free ones).
Number of free pencils that Cody could get
= 20 ÷ 6
= 3 r 2
Total number of pencils that Cody could get
= 20 + 3
= 23
Answer(s): (a)
110; (b) 23
