M3.4.3 For the adult
Sharing in a ratio
Amina and Ravi share 35 seeds in the ratio 2 : 5. How many seeds does each one get?
What this chapter teaches
To share in a ratio, add the parts, find the size of one part, then multiply. If one share is known, it gives one part, and one part gives the total.
Three questions to ask
There is no one right wording. Listen for the idea.
- How many equal parts are there when you share in the ratio 2 : 5?
- Why is it wrong to give one person 2 seeds and the other 5 seeds?
- How can you check that the two shares are right?
After the chapter, the learner can
- Share 35 seeds in the ratio 2 : 5
- Find the total when you know the size of one share
What they copy into their notebook
Add the parts. Divide the total by the number of parts to find one part. Multiply one part by each share. Check that the shares add up to the total.
