Thanks Mrs Wong:)

mrswongtuition:

The distance between Town A and Town B is 12 km 400 m and between Town A and Town C is 26 km. Tom travelled from Town A to Town B and then returned to Town A before going to Town C. What was the total distance Tom travelled?

It's not a trick question.

|---------------26km-----------------|
|----12km400m----|----------------|
A`````````````B``````````C

Tom travelled from Town A to Town B
From Town A to Town B = 12km 400m

then returned to Town A
From Town B to Town A = 12km 400m

before going to Town C
From Town A to Town C = 26km

TOTAL DISTANCE TRAVELLED:
12km400m + 12km400m + 26km = 50km 800m

Hi,

Anyone can solve this:

Ali spent 1/3 of his saving on a pen. He spent 1/4 of the remainder on a book. If he had $38 left, how much he have at the beginning ?

Ali's Savings:
[/////][-----][-----]
[Pen ][remainder]

1/4 of 2 units = 1/2 unit
Redraw the model:
[///][///][---][---][---][---]
[--pen--][---remainder---]
```````[bk ]

Now, 1/4 of the remainder is used to buy a book.
Which means the Ali has a total of 6 units in savings and has 3 units left.

3 units = $38
6 units = $38 x 2 = $76

Dear Parents,

Are you frustrated/stuck when helping your child solve his/her Maths questions? Are you inclined to use Algebra most of the time? Do you have difficulty trying to use diagrams or other heuristic methods (that Primary School students learn) to solve?

:idea: Post your questions here and see how MathsGuru solve them to the best of her ability. Detailed solutions will be posted back in this thread.

So start asking and watch this space!!

You should post this in the Mathguru's thread

Another question 4)


2/5 of Limin's money can buy 40 books. How many books can she buy with 3/4 of her money?

Thanks !

2/5 =8/20
¾ = 15/20

2/5 (or 8/20) of her money => 40 books
1/20 of her money => 5 books

So,
¾ (or 15/20) of her money => 15 x 5 = 75 books

2. Mary bought a leather bag with 3/7 of her money. She spent the remainder on 14 pairs of socks which cost $6 each pair. How much was the leather bag?

Q1)
Remainder after donating to charity = 3/5 x $145 = $87
Gave to sister => 1/6 x $87 = $14.50

Q2)

Remainder after buying leather bag => 14 x $6 = $84

Remainder => 4/7 of her money = $84
Cost of leather bag => 3/7 of her money = $84/4 x 3 = $63
