PSLE Julian spent
13 of his money to buy 3 identical markers. He spent the rest of his money to buy another 5 such markers and 3 identical staplers.
- What fraction of Julian's money was spent to buy the 3 staplers? Give your answer in the simplest form.
- For every 4 staplers bought, 1 additional stapler was given free. How many staplers would Julian get in total if he were to spend all his money to buy staplers only?
(a)
Cost of 3 markers =
13 of his money
Cost of 1 marker
=
13 ÷ 3
=
13 x
13 =
19 of his money
Cost of 5 markers
= 5 x
19 =
59 of his money
Fraction of Julian's money spent to buy the 5 markers and 2 staplers
= 1 -
13 =
23 Fraction of Julian's money spent to buy the 3 staplers
=
23 -
59 =
69 -
59 =
19 (b)
19 of Julian's money = 3 staplers
99 of Julian's money = 9 x 3 = 27 staplers
Number of free staplers
= 27 ÷ 4
= 5 r 2
Total number of staplers that Julian would get
= 27 + 5
= 32
Answer(s): (a)
19; (b) 32
