PSLE Gabriel used
47 of his money to buy 8 markers. He used the rest of his money to buy 5 markers and 4 pencils.
- What fraction of his money did Gabriel use to buy the 4 pencils?
- If 1 pencil was given for free for every 3 pencils bought, how many pencils would Gabriel be able to buy if he were to use all his money to buy pencils?
(a)
Fraction of his money used to buy 5 markers and 4 pencils
= 1 -
47 =
37 8 markers →
47 of his money
1 pen →
47 ÷ 8 =
114 of his money
5 markers → 5 x
114 =
514 of his money
5 markers + 4 pencils →
37 of his money
4 pencils →
37 -
514 =
614 -
514 =
114 of his money
(b)
4 pencils →
1141 pencil →
114 ÷ 4 =
156 of his money
If 1 pencil cost
156 of his money, Gabriel could buy 56 pencils (Not including the free ones).
Number of free pencils that Gabriel could get
= 56 ÷ 3
= 18 r 2
Total number of pencils that Gabriel could get
= 56 + 18
= 74
Answer(s): (a)
114; (b) 74
