There were 24 marks on the number line for each multiple of 5 , plus he needs a marker for the zero
so 25 numbers were listed.
e.g. from 0 to 10 would be 3 , that is 10/2 + 1
from 0 to 20 would be 5 , that is 20/5 + 1
0---5---10---15---20
so 25 numbers were listed.
e.g. from 0 to 10 would be 3 , that is 10/2 + 1
from 0 to 20 would be 5 , that is 20/5 + 1
0---5---10---15---20
