Not necessarily. All rational numbers are real, not all real numbers are rational.
The square root of -25 is not a real number, as it involves taking the square root of a negative number which results in an imaginary number. In this case, the square root of -25 is 5i, where i represents the imaginary unit. Since rational numbers are a subset of real numbers, the square root of -25, being an imaginary number, is not a rational number.
The square root of 8 over 25 is irrational, and real.
A real number dosen't have to be a rational number as a real number can be rational or irrational i.e the root of 2 is irrational and real. So is (pi).
Yes. -3 is both rational and real. -3 is an integer. All integers are rational numbers. All rational numbers are real numbers. Thus -3 is a rational number and a real number.

Sometimes. The number '4' is real and rational. The number 'pi' is real but not rational.

Decimals are real. They can be rational or irrational.
what is the rational number for 2/25
Yes. -3 is both rational and real. -3 is an integer. All integers are rational numbers. All rational numbers are real numbers. Thus -3 is a rational number and a real number.
A real number which is not a rational number is an irrational number.
4/25 squared is 16/625 = 0.0256 . That's a perfectly rational number.
Yes it is, but not every real number is a rational number
Yes, 34 is a real and rational number
