PSLE John used
35 of his money to buy 6 notebooks. He used the rest of his money to buy 3 notebooks and 4 pencils.
- What fraction of his money did John use to buy the 4 pencils?
- If 1 pencil was given for free for every 6 pencils bought, how many pencils would John be able to buy if he were to use all his money to buy pencils?
(a)
Fraction of his money used to buy 3 notebooks and 4 pencils
= 1 -
35 =
25 6 notebooks →
35 of his money
1 pen →
35 ÷ 6 =
110 of his money
3 notebooks → 3 x
110 =
310 of his money
3 notebooks + 4 pencils →
25 of his money
4 pencils →
25 -
310 =
410 -
310 =
110 of his money
(b)
4 pencils →
1101 pencil →
110 ÷ 4 =
140 of his money
If 1 pencil cost
140 of his money, John could buy 40 pencils (Not including the free ones).
Number of free pencils that John could get
= 40 ÷ 6
= 6 r 4
Total number of pencils that John could get
= 40 + 6
= 46
Answer(s): (a)
110; (b) 46
