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.

From Ai Tong Pri 3 SA1 Maths:


A teacher gave her students some balloons. If she gave 6 balloons to each student, she will have 2 balloons left. If she gave 8 balloons to each student, she will be short of 2 balloons. What is the smallest possible number of students she has?

Try to do this without using ALGEBRA!

Excess+Shortage
______________ = No. Of Students
Difference

So,

2+2=4
4/2=2

So, the answer is 2.
