Todos son números racionales.
Step-by-step explanation:
Un número racional tiene la forma de p / q donde pyq son números enteros y q ≠ 0.
Por ejemplo, un número 1/3 es un número irracional porque es un número decimal recurrente, es decir, puede continuar después del decimal (0.13333333)
Pero los números como 1/5 o 1/2 que no son recurrentes son números racionales.
Todos los números dados 1 / 2,0, 3.8 y 7.2 son números racionales ya que cada uno puede expresarse en forma de p / q
Números p q p / q
1/2 1 2 1/2 = 0,5
0 0 cualquier entero 0
3,8 19 5 19/5 = 3,8
0,72 72100 0,72
Por tanto, todos son números racionales.
English
A rational number is in the form of p/q where p and q are integers and q ≠ 0.
For example a number 1/3 is an irrational number because it is a recurring decimal number i.e it can continue after the decimal ( 0.13333333)
But numbers such as 1/5 or 1/2 which are non recurring are rational numbers.
All the numbers given 1/2,0 ,3.8 and 7.2 are rational numbers as each can be expressed in the form of p/q
Numbers p q p/q
1/2 1 2 1/2=0.5
0 0 any integer 0
3.8 19 5 19/5=3.8
0.72 72 100 0.72
Hence all ae rational numbers.
