PSLE Eric used
23 of his money to buy 6 staplers. He used the rest of his money to buy 2 staplers and 5 markers.
- What fraction of his money did Eric use to buy the 5 markers?
- If 1 marker was given for free for every 6 markers bought, how many markers would Eric be able to buy if he were to use all his money to buy markers?
(a)
Fraction of his money used to buy 2 staplers and 5 markers
= 1 -
23 =
13 6 staplers →
23 of his money
1 pen →
23 ÷ 6 =
19 of his money
2 staplers → 2 x
19 =
29 of his money
2 staplers + 5 markers →
13 of his money
5 markers →
13 -
29 =
39 -
29 =
19 of his money
(b)
5 markers →
191 marker →
19 ÷ 5 =
145 of his money
If 1 marker cost
145 of his money, Eric could buy 45 markers (Not including the free ones).
Number of free markers that Eric could get
= 45 ÷ 6
= 7 r 3
Total number of markers that Eric could get
= 45 + 7
= 52
Answer(s): (a)
19; (b) 52
