It is rational.
It is a rational number because it can be expressed as a fraction in the form of 75/1
4.6 is rational.
7.5 is the ratio of 75 to 10, so it's rational.
The square root of (any number that isn't a perfect square) is irrational.
It is a rational number.
No. The square root of most numbers is irrational - only if the number of which you take the root happen to be perfect squares, do you get a rational root. In this case, to take the square root of 3/4, 3 is not a perfect square, so the root is not rational. Or you can take .75 to be 75/100; once again, 75 is not a perfect square, so the root is irrational.
No, 3.56 is not an irrational number. 3.56 is rational.
75 times 75 = 5625 which is a rational number
it is a rational number but 4.121314..... is an irrational no
1.14 is rational.
It is rational, as it is possible to express it as a fraction.
No, it is rational.
If x is rational the it is rational. If x is irrational then it is irrational.
No, because it is a rational number that can be expressed as a fraction in the form of 3/4
5.2 is rational. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
No. A rational plus an irrational is always an irrational.
No, they are disjoint sets: no rational is irrational and no irrational is rational.
