PSLE Daniel used
23 of his money to buy 6 staplers. He used the rest of his money to buy 2 staplers and 4 notebooks.
- What fraction of his money did Daniel use to buy the 4 notebooks?
- If 1 notebook was given for free for every 5 notebooks bought, how many notebooks would Daniel be able to buy if he were to use all his money to buy notebooks?
(a)
Fraction of his money used to buy 2 staplers and 4 notebooks
= 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 + 4 notebooks →
13 of his money
4 notebooks →
13 -
29 =
39 -
29 =
19 of his money
(b)
4 notebooks →
191 notebook →
19 ÷ 4 =
136 of his money
If 1 notebook cost
136 of his money, Daniel could buy 36 notebooks (Not including the free ones).
Number of free notebooks that Daniel could get
= 36 ÷ 5
= 7 r 1
Total number of notebooks that Daniel could get
= 36 + 7
= 43
Answer(s): (a)
19; (b) 43
