Yes. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
2/5 are prime, 8/15 are composite (and 1/15 is neither).
Pi is not prime nor composite, instead, it is what is called irrational (It can't be written as a fraction or whole number.) Because only whole numbers can be prime, pi is not prime.
it can't be reduced.
Yes. If the numerator and denominator of a fraction are prime, the fraction is in simplest form. The reason is that each number has only two factors, 1 and the number itself. For that reason, it is not possible for the numerator and denominator to have any factors (other than 1) in common.
40 out of 103 is a fraction. Prime numbers are whole numbers. A fraction cannot be a prime number, so 40 out of 103 is not a prime number.
Yes, a prime number can be used in a fraction. For example, 7/9, where 7 is the prime number. Or 7/13, where both are prime numbers.
Yes. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
29 is rational. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
No - prime numbers are integers - a fraction cannot be a prime number.
2/5 are prime, 8/15 are composite (and 1/15 is neither).
All prime numbers are rational number because they can be expressed as 'top heavy' fractions as for example the prime number 3 as a fraction is 3/1
9 natural numbers. 4/9 are prime. (this ryhmes)
-23 is rational. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
If one of the numbers is prime and doesn't go into the other number Or the numbers have no common factors.
3/10 are prime.
Pi is not prime nor composite, instead, it is what is called irrational (It can't be written as a fraction or whole number.) Because only whole numbers can be prime, pi is not prime.
