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.

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.

Hi,

2 + 6 = 8

1 --> 8
2 --> 14

- 2 + 8 = 6

1 --> 6
2 --> 14 (matched above number of balloons)

So there are 2 students.

Please help me with the following P4 qtn.



24 guavas and 130 oranges in a basket had a mass of 10.27 kg. When 5 guavas and all the oranges are taken out, the mass became 4.07 kg. Each guava has a mass 5 times as much as each orange. Find the mass of the basket when it is empty, in grams.


Thanks!
