Test theories with smaller numbers

eg

How many multiples of 6 are between 10 and 50?  I have chosen numbers that are not multiples of 6 (like your question)

My guess is  (50-10)/6 = 6 and a bit.  So I am guessing 6 or  7

12,18, 24, 30, 36,42,48    It is 7 I had to round up.

Another example

How many multiples of 6 are between 10 and 40?  I have chosen numbers that are not multiples of 6 (like your question)

about (40-10)/6 = 5    That is spot on.

Now you tell me what your one will be.
