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