Yes,
All integers are rationals because they can be written as a fraction N/1 where N is the integer.
The converse, or opposite is NOT true. Not all rationals are integers.
For example, 2/3, 1/2, and 12/5. Surely you can think of many , many more...
So the Venn diagram. the circle for INTEGERS shall be ENTIRELY INSIDE
the circle for RATIONALS.
