1,2,5,10 are all common factors of 90 and 80
There are an infinite amount of numbers between 5 and 10 if you consider decimal positions.
However, if you're referring to whole numbers (example: 5, 25, 200, etc)
There are 4 numbers between 5 and 10:
6, 7, 8, and 9.
Depends on the answers it gives you, you can do 50 + 2 or (10 x 5) + 2 >.< That is how I learned anyway and I think thats what you mean
