Who Gets what?
John receives $24.50 and Bill receives 50 cents.
Using the ‘guess and check’ method, it goes like this:
- Try $24 and $1 – the first part is 24 times the second part. Not quite enough!
- Now halve the $1 to give two lots of 50 cents and add one lot to John’s $24.00.
- Now John’s part is $24.50 and Bill’s part is 50 cents.
- John has 49 times as much as Bill. Poor Bill He didn’t do very well out of that!
(Dividing a number by a half is the same as multiplying it by 2. that means that dividing $24.50 by 50 cents (half a dollar), we get the result 49.
Mathematicians, of course, will set up a pair of simultaneous equations and solve them that way!
