Q&A - P4 Math

Hi Chokos,


You can try seeing the qn in this way.

At first, Pamela has $300 less than Jessica.
After Pamela spent her $60, she will now have $360 less than Jessica.
So 5u = $360, 1u = $72
Money Pamela had at first = $72 + $60 = $132.

Hope this helps.

Hi

answer is 252 if you are looking for the largest number that is less than 270. The number is divisible by both 6 & 7, so it has to be divisible by 42. The largest multiple of 42 that is less than 270 = 42 x 6 = 252.

cheers.

Hi

You may use MD.

Draw a bar to show plates and sub divide into 8 units.
5 units ----- sold
3 units ----- left

Draw another bar below the first one.
12 ------ sold
3 units ------ left

11 units + 12 ------100
11 units ------- 88
1 unit ------ 8

Number of bowls at first ------3 units + 12 ------- 36

Hi

You may use MD.

Draw 2 boxes to show the number of votes for Belinda.
Ada ------- 1box
Tina ------ 1 box
Susan ------ 1 box + 100

Tina had had as many votes as Ada but 60 fewer votes than Belinda.\t
Hence, 1 unit ------ 60\t

Number of people who voted ------5 units + 100 ------ 300 + 100 -----400
\t
Belinda ------- 120
Ada ------- 60
Tina ------- 60
Susan ------ 160
