4/5 of squids -> 3/4kgbelnanna wrote:I need help please.. Thanks in advance!

Mr Ho fried 1/5 of his squids and had 3/4 Kg of squids left. How many kg of squids did he fry?

1/5 of squids -> 3/4 divided by 4 = 3/4*1/4 = 3/16kg

Hi kindly answer this

A tailor had some cloth she used 2/9 of the cloth to make dresses and 3/14 of the remaining cloth to make trousers. She bought another 126m of cloth and then found out that she had as much cloth as she had at first. Find the length of the cloth tailor had at first.

Let's try; one possible method:

Look at the denominators; 9 and 14.

9 x 14 = 126

Let the tailor have 126 units (or 126 u) of cloth at first.

She used 2/9 of the cloth to make dresses.

She used 28 u of the cloth to make dresses.

She had 98 u left.

She used 3/14 of the remaining cloth to make trousers.

She used 21 u of the cloth to make trousers.

She had 77 u left.

She bought another 126m of cloth and then found out that she had as much cloth as she had at first.

77 u + 126m → 126 u

126m → 49 u

49 u → 126m

1 u → (126/49) m

126 u → 126 x (126/49) m →

The tailor had

Hope this helps.

Cheers

Hi,leng2005 wrote: Please help me.

This is a "Double-Ratio" question:

you can use the "Advanced Model Method" or "Bags and Boxes" method to solve ALL (100% of) such P5 maths problems.

You can also use the more algebraic version of "u and p."

Let Veronica put her $91 into 1 Bag and 4 Boxes.

$91 → 1 Bag + 4 Boxes ..... (Row 1)

Let Benny put his $28 into 1 Bag and 1 Box.

$28 → 1 Bag + 1 Box ........ (Row 2)

Veronica spent 1 Bag of money, and had 4 Boxes left.

Benny also spent 1 Bag of money, and had 1 Box left.

(Row 1) - (Row 2)

($91 - $28) → (1 Bag - 1 Bag) + (4 Boxes - 1 Box)

($63) → (0 Bag) + (3 Boxes)

3 Boxes → $63

1 Box → $21

Benny had

Parents who wish to find out more about the "

(2)

Some schools use “Bags and Boxes”,

Some schools use the algebraic version of “u” and “p”.

Students may use either version; whichever that they find easier.
