{-5, -2.7777..., 3, 0, -5.27}
Any number with a recurring decimal (or recurring decimals such as 0,157815781578... is rational. Any number with a terminating decimal is rational.
A rational number is simply any number that can be written as an integer over an integer. -5 = -5/1; -2.777... = -25/9, 3 = 3/1, 0 = 0/1, -5,27 = -527/100.
Pi cannot be written as an integer over an integer. There is also no repeating pattern in the decimals and they never terminate).
All except pi are rational numbers.
Even the -2.7777777777..... is rational
