Hi,


Problem sum question need help.
\"David has 5/8 as many stickers as Vincent. They have a total of 494 stickers.
a) How many stickers must Vincent give to David so that both of them will have the same number of stickers?
b) How many stickers does Vincent have in the end?

How to draw the model?

Is the quest said, David has 5/8 stickers and Vincent has 8/8 stickers??

Thanks...

David has [][][][][]
Vincent has [][][][][][][][]
Total 13[]
494 stickers divide by 13 = 38 stickers

Vincent has 38 x 8 = 304
David has 38 x 5 = 190

a) 494 divide by 2 = 247
Therefore Vincent must give David 247-190=57 stickers

b) Vincent has 304-57=247 in the end.

David has 5 Units

Vincent has 8 units
Total 13 Units

1 unit = 494/13 = 38 stickers

(8 Units + 5 units)/2 = 6.5 Units

Davud must give Vincent = (8- 6.5) Units
= 1.5 units
= 1.5 x 38 stickers
= 57 stickers

Therefore Vincent must give David 57 stickers

b) Total nos. of Vincent stickers = 38 x 8 units = 304 stickers

Vincent has 304-57=247 in the end.

Base on your model. Vincent has 8/8 stickers


Thanks alot :love:

Hi,


I got a question to ask:

I always thought that when you see the word ‘place’ ie. The digit 8 is in the _________ place, it means answers like ‘thousands’, ‘hundreds’ etc are required; and when they ask for ‘value’ ie. What is the value of ‘8’, it means it wants answers like ‘8000’.

How about ‘place value’? ‘Thousands’ or ‘8000’?

You thought right in the first place. Pardon the pun. :lol: Take for example a given set of numbers - 18452. For place value, it means how much the digit 8 represents which in this case 8000 or 8 thousands. Another way this question is asked is \"What does the digit '8' stands for?\"

Hi please help.


Daisy had twice as many pencils as Sulin at first. Then Rose gave 8 pencils to Sulin. After that, Rose had three times as many pencils as Sulin. If Daisy, Sulin and Rose had 134 pencils altogether, how many more pencils than Daisy did Rose have at first?

Thanks!!!

Before
D : S = 2U : 1U

After
R : S = 3V : 1V

Since the After of 'Sulin' is 8 more than Before, 1V = 1U + 8

So 3V = 1U+8+1U+8+1U+8 = 3U + 24 [Rose 'After']

The Total pencils is :
D (after is same as before) + R (after) + S (after)
= (2U) + (3U+24) + (1U+8 )
= 6U + 32

Since total is 134, therefore :
6U + 32 = 134
6U = 102
1U = 17

Before of D is 2U = 34
After of Rose is (3U+24) = 3x17 + 24 = 75
Before of Rose = 75 + 8 = 83

Difference between Daisy and Rose = 83 - 34 = 49
