Answer:
Step-by-step explanation:
If x is such an irrational number then
1 / 7 < x < 2 / 7
=> 1 / 49 < x² < 4 / 49
One such number is the one with
x² = 2 / 49.
The corresponding value of x is
√2 / 7
which is then an irrational number between 1/7 and 2/7.
(Notice this same choice could have been made by taking the geometric mean of 1/7 and 2/7, if that's something you're familiar with.)
yes you

I hope I understood your question correctly. That the irrational needs to be 1/7 and 2/7. If not, sorry, I guess my response isn't helpful then!
Great!
