Hi, if there were 26 cookies, how can it be shared equally among 9 children? I thought it's a guess and check question. My answer is 18 cos' I thought each child will get 2 cookies if shared among 9 to share among 13 children, we need 8 more cookies. Correct me if I'm wrong.

Hi

I left the answer as 26 per children earlier.

sorry, should be 18*13 = 234 or 26*9 = 234

The answer is 234 cookies

Pls help me with this question :

Dist AD = 2m, Dist DE = 5/8 m

Dist AB = Dist BC = 1/4 m

So, Dist CD = Dist AD - Dist AC = 1(1/2) m

Then, Dist BE = Dist DE + Dist BC + Dist CD
= 5/8 + 1/4 + 1(1/2) = 19/8 m = 2(3/8) m

Try labelling the respective lengths on the diagram and it'll be clearer

Thanks, i kept thinking of converting the fraction into cm.

I know this is a very simple question.


Q) A can of orange juice is 300ml. What is the minimum number of cans needed to fill up a container with a capacity of 2 litres?

Ans: 7

Isn't \"6\" the minimum? My kid argued that \"7\" cans would be overspilled already! :roll:

Appreciate some clarification.

Hi

Use 200ml from the seventh can.
