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>

Jessica can swim a lap and 29 and 2/5 second Marta can swim a lap in 28.7 seconds how much faster can marta swim lap and then Je
Vladimir79 [104]

Alright, lets get started.

Jessica can swim a lap in 29\frac{2}{5} seconds

Converting it into decimals, 29+\frac{2}{5}

Means 29+0.4 = 29.4 seconds

Means Jessica can swim a lap in 29.4 seconds

Marta can swim a lap in 28.7 seconds.

So, Martha is faster than Jessica by 29.4-28.7=0.7 seconds

It means Marta is 0.7 seconds faster than Jessica.   :  Answer

Hope it will help :)
