hey...
You have to play around with the numbers.
First, notice the factors of the numbers.
10 = 2 x 5
8 = 2 x 2 x 2
5 = 5
1 = 1
1 = 1
In order to make 10, you need to combine the 5 with the factor of 2 from 8. You somehow want to get rid of the remaining 2×2 factor from 8. But how do you do that?
You can experiment with some values. Consider all the values you can get by dividing two numbers. The possible answers are:
8/5
5/8
5/1
1/5
The last choice 1/5 is interesting because 1 – 1/5 = 4/5. So this gives you the 4 = 2×2 factor, and now you combine it cleverly with the 8.
