En un acuario compraron 30 peces y 18 tortugas de agua. Los van a colocar en peceras. Cada una tiene que haber la misma cantidad
seraphim [82]

Answer:

a) ¿Cuántas peceras compraron?

Según el cálculo anterior, la cantidad de peceras que compró es de 90 peceras.

b) ¿Cuántos peces y tortugas puede tener cada tanque?

3 peces por tanque

5 tortugas de agua por tanque

Step-by-step explanation:

Resolvemos la pregunta anterior utilizando el cálculo de múltiplo común más bajo

En un acuario compraron 30 peces y 18 tortugas de agua.

Encuentre y enumere los múltiplos de cada número hasta encontrar el primer múltiplo común. Este es el mínimo común múltiplo.

El mínimo común múltiplo es el número de tanques

Múltiplos de 18:

18, 36, 54, 72, 90, 108, 126

Múltiplos de 30:

30, 60, 90, 120, 150

Por lo tanto,

MCM (18; 30) = 90

a) ¿Cuántas peceras compraron?

Según el cálculo anterior, la cantidad de peceras que compró es de 90 peceras.

b) ¿Cuántos peces y tortugas puede tener cada tanque?

El número de peces que puede tener cada tanque = Número de tanques / Número de peces

= 90/30

= 3 peces por tanque

El número de tortugas de agua que puede tener cada tanque =

Número de tanques / Número de tortugas de agua

= 90/18

= 5 tortugas de agua por tanque

Sandra recieved 15 $20 bills for her birthday. She spent 3/5 and saved 2/5 how much did Sadra spend and how much did she save.
julia-pushkina [17]
The first step to solving this problem is to find out how much money Sandra received for her birthday. We can find this out by multiplying 15 by 20,, which will look like the following:
15 x 20 = 300
Now that we know that Sandra received a total of $300 for her birthday,, we need to multiply the 300 by \frac{3}{5} to see how much she spent.
300 x \frac{3}{5}
First we need to reduce the numbers with 5
60 x 3
Then multiply the numbers together to find out how much money Sandra spent
180
Now,, we need to multiply 300 by \frac{2}{5} to see how much of her money she saved
300 x \frac{2}{5}
Reduce the numbers with 5
60 x 2
Then multiply the numbers together to see how much money Sandra saved.
120.
This means that Sandra spent $180 and saved $120.
