PSLE George used
47 of his money to buy 8 files. He used the rest of his money to buy 5 files and 4 pens.
- What fraction of his money did George use to buy the 4 pens?
- If 1 pen was given for free for every 6 pens bought, how many pens would George be able to buy if he were to use all his money to buy pens?
(a)
Fraction of his money used to buy 5 files and 4 pens
= 1 -
47 =
37 8 files →
47 of his money
1 pen →
47 ÷ 8 =
114 of his money
5 files → 5 x
114 =
514 of his money
5 files + 4 pens →
37 of his money
4 pens →
37 -
514 =
614 -
514 =
114 of his money
(b)
4 pens →
1141 pen →
114 ÷ 4 =
156 of his money
If 1 pen cost
156 of his money, George could buy 56 pens (Not including the free ones).
Number of free pens that George could get
= 56 ÷ 6
= 9 r 2
Total number of pens that George could get
= 56 + 9
= 65
Answer(s): (a)
114; (b) 65
