De un total de 24 niñas 1/4 practican natación, 1/2 juega volibol y el resto no practica ningún deporte. ¿Cuántas niñas no pract
masya89 [10]

Answer:

6 niñas no practican ningún deporte.

Step-by-step explanation:

De un total de 24 niñas, \frac{1}{4} practican natación. Esto se expresa mediante la operación matemática:

\frac{1}{4} *24

Para multiplicar una fracción por un número entero, cualquier entero n puede ser escrito como la fracción \frac{n}{1}. Entonces en este caso:

\frac{1}{4} *24=\frac{1}{4} *\frac{24}{1}

Ahora se multiplican los denominadores para obtener el denominador final y se multiplican los numeradores para obtener el numerador final:

\frac{1}{4} *24=\frac{1}{4} *\frac{24}{1}=\frac{1*24}{4*1}=\frac{24}{4}

Finalmente, se reduce el resultado hasta llegar a la forma más simple. Para obtener un resultado simplificado, se divide el numerador por el denominador.  En este caso, para reducir la fracción \frac{24}{4}, se divide 24 por 4. El resultado obtenido es 6. Esto indica que de un total de 24 niñas, 6 practican natación.

Por otro lado, de un total de 24 niños, \frac{1}{2} juegan voleibol. Esto se expresa mediante la operación matemática:

\frac{1}{2} *24

Resolviendo de manera similar a lo previamente calculado, se obtiene:

\frac{1}{2} *24= 12

Esto indica que de un total de 24 niñas, 12 practican voleibol.

Por lo que 6 niñas practican natación y 12 voleibol, siento un total de 18 niñas las que practican algún deporte. Por lo que la cantidad de niñas que no practican ningún deporte se calcula mediante:

24 niñas - 18 niñas que practican algún deporte= 6 niñas

<u><em>6 niñas no practican ningún deporte.</em></u>

What type of number is 1/2?
makkiz [27]

Answer:

1/2 is a rational number.

Step-by-step explanation:

Real numbers are numbers that can represent "distance" along a line. The set of real numbers has subsets that include natural numbers, whole numbers, integers, and rational numbers.

Natural numbers are counting numbers. A.K.A., they are numbers that you would start counting your fingers on (1, 2, 3, ...)

Whole numbers are just natural numbers and 0.

Integers are whole numbers and their opposite. (..., -3, -2, -1, 0, 1, 2, 3, ...)

Rational numbers are integers and numbers that can be put into a fraction of two integers. For example, 3/4 is a fraction of two natural numbers (3 and 4) who are also integers. Therefore, 3/4 is a rational number.

So, what number is 1/2?

It can't be a natural number because no one counts numbers as fractions unless they were made to.

It can't be a whole number because 1/2 is not whole. It is half of 1.

It can't be an integer because integers include whole numbers and their opposites, and 1/2 isn't even a whole number.

1/2 has to be an rational number because it is a fraction of two integers, 1 and 2.
