Answer:

A rational number is a number that can be written as a fraction.

A. 7.11

=> 711/100

So, the 1st option is a rational number.

B. 4.333....

=> 4 1/3

=> 13/3

So, the 2nd option is a rational number.

C. 8/11

=> This is in its fractional form.

=> So, the 3rd option is a rational number.

D. -2852664798743

=> This can't be written in a fractional form.

=> So, the 4th option is NOT a rational number.
