Jonah drives from his car to and from work. The total length of the trip to and from work is 19.2 miles. In August, Jonah worked
natita [175]
ANSWER

The total length of the trip to and from work in August is

403.2 \: miles

EXPLANATION

The total length of the trip to and from work is

19.2 \: miles

If Jonah worked 21 days in August,

Then, the total length of the trip to and from work is
= 21 \times 19.2 \: miles

Change the decimal to fraction and multiply,

= 21 \times \frac{192}{10} miles

= \frac{21 \times 192}{10}

= \frac{4032}{10} miles

Convert back to decimal

= 403.2 \: miles

Felipe, Pedro y Miguel son fanáticos del cine. Felipe asiste cada 3 días; Pedro cada 6 días y Miguel cada 5 días. Los tres van j
lilavasa [31]

Answer:

Opción C, 30 días.

Step-by-step explanation:

Sabemos que:

Felipe asiste al cine cada 3 días

Miguel asiste cada 5 días.

Pedro asiste cada 6 días.

Los tres van juntos un día,  ¿dentro de cuántos días irán otra vez juntos?

Los 3 volverán a ir juntos luego de N días, tal que N es el menor múltiplo común de 3, 5 y 6.

Como 6 es múltiplo de 3, podemos ignorar al 3, y solo considerar al menor múltiplo en común de 5 y 6.

Además, como podemos reescribir estos números como un producto de números primos, así obtenemos:

6 = 2*3

5 = 5*1

Estos números no comparten factores entre ellos, por lo que el menor múltiplo entre 5 y 6 es simplemente 5*6 = 30

Entonces podemos concluir que N = 30

Felipe, Pedro y Miguel irán juntos al cine nuevamente dentro de 30 días.

La opción correcta es C.
