Ratio - Lesson 1


Dear 5B,

Today we had our first official lesson on Chapter 5-Ratios in the microlab. (Wow~ air-conditioned!)

These were the objectives of the lesson:
At the end of the lesson, pupils will be able to
1) interpret ratio a:b where a and b are whole numbers
2) write equivalent ratios
3) express a ratio in its simplest form

Your task
Post a comment about what you have learnt in the lesson. You may want to give some examples to explain your write-up.
Remember to indicate your name before you post your comment.

    I have learned how to use ratio. I have also learned that ratio can be simplified. I would like to learn more about ratio in class!

    Sorry for the interruption, Wai Yee, I think you are wrong. Your example '2:6:9' is possible in ratio.

    Okay, you can continue..................

    I think nathan is right. I have learned ratio in my Tution class and ratio can be written as '2:3:4'.

    Yes, ratio can be written like this ':2:5:7'
    We can compare more then two things in 1 ratio.

    Why is Wai Yee the leader here? I don't know anything about ratio. And I agree & disagree with all of you. When are we going to finish this topic? Ans by the way, I have a new question. Does ratio only compare time? I can't believe i'm the latest one to comment!

    "Nah,you are not the last one to comment.I posted this much much later than you,Fahim" By the way, 'think that ratio can be written in three numbers e.g:1:2:3.Hey,ratio usually CANNOT be to compare time.Only weight,height,no. of things in one group to another group,like what I posted yesterday night.Too bad Mrs Ang didn't pick me.If not, I could have got a bag from her.

    Haha... ratio is a way to compare objects. If you have to compare two types, then A:B. If you have 3 different types, then A:B:C.

    We have used ratio to compare apples and oranges. So Fahim, you cant say that ratio is used to compare time only.
