PSLE Cole used
23 of his money to buy 6 pencils. He used the rest of his money to buy 2 pencils and 3 markers.
- What fraction of his money did Cole use to buy the 3 markers?
- If 1 marker was given for free for every 4 markers bought, how many markers would Cole be able to buy if he were to use all his money to buy markers?
(a)
Fraction of his money used to buy 2 pencils and 3 markers
= 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 markers →
13 of his money
3 markers →
13 -
29 =
39 -
29 =
19 of his money
(b)
3 markers →
191 marker →
19 ÷ 3 =
127 of his money
If 1 marker cost
127 of his money, Cole could buy 27 markers (Not including the free ones).
Number of free markers that Cole could get
= 27 ÷ 4
= 6 r 3
Total number of markers that Cole could get
= 27 + 6
= 33
Answer(s): (a)
19; (b) 33
