Which of the following numbers is irrational?
A 5/9
B 3.15
C /5
D 8.341
I THINK IT A
CAN SOMEBODY HELP ME
a rational number can be written as a fraction.
Any terminating or repeating decimal is also rational.
√5 is not rational. There is no fraction which is exactly equal to √5. The decimal value goes on forever and never repeats.
It is easy to prove that √5 is irrational, if you are interested. Just google proofs for √2 and follow the same logic you find there.
so it c
To determine whether a number is irrational, we need to understand the definition of an irrational number. An irrational number is a number that cannot be represented as a fraction, where the decimal representation neither terminates nor repeats.
Let's examine each option:
A: 5/9 is a rational number because it can be expressed as a fraction.
B: 3.15 is a rational number because it can be expressed as a terminating decimal.
C: /5 seems to be an incomplete option. Please provide the complete number for a proper evaluation.
D: 8.341 is a rational number since it can be expressed as a terminating decimal.
Based on the options you provided, it seems none of them are irrational numbers. It is also worth noting that if option C were to be properly given, irrational numbers are usually denoted by square roots of prime numbers that are not perfect squares. For example, √2 is an irrational number.
