I had a doubt Is 4/8 a rational number
Because my text book says that a rational number must have no other common factor than 1
But 4/8 has a common factor of 2
4/8=1/2
1/2 is rational but is 4/8 rational?

yes

Step-by-step explanation:

Since 4/8 and 1/2 are the same number and you know that 1/2 is rational, that means that 4/8 is also rational.

4/8 is rational

Step-by-step explanation:

Since teachers and other sources will tell you to simply the fraction down, you will get 4/8 equal 1/2. If they are the same value, and 1/2 is rational, then 4/8 is rational as well.
