2 rational numbers are C. 2.777 and D. -7/3

a rational number is any number that can be expressed as the quotient or fraction p/q of two integers

as you know 0.7777 (7 repeat) = 7/9
so 2.777(7 repeat) = 2 7/9

a rational number is any number that can be expressed as the quotient or fraction of two integers. so i think all of them are rational numbers except B.
