Answer:

15 boys and 20 girls

Step-by-step explanation:

1. Since we cant simplify 3:4 we will leave it just like that.

2. 3x+4x=35

3. We add them both to give us 7x=35

4. We divide by 7 to get x by itself which results in 35/7=5.

x=5

5. Now we found x we can create 2 seperate soulutions:

3(5)=

and 4(5)=

Therefore there are 15 boys and 20 girls in the class. This makes sense because 15/20 reduced is 3 over 4.

343 or how to solve LCM OR GCF Since 1 divides into everything, then the greatest common factor in this case is just 1. When 1 is the GCF, the numbers are said to be "relatively" prime; that is, they are prime, relative to each other. Then the GCF is 1 and the LCM is 2 × 2 × 2 × 3 = 24.

Si 15 obreros construyen un muro en 45 minutos, ¿en cuánto tiempo lo construirán 3 obreros con similar habilidad?
Alexxx [7]

Answer:

3 obreros tardaran 225 minutos en completar el trabajo.

Step-by-step explanation:

Sea R la velocidad con la que un obrero puede construir 1 muro.

Sabemos que 15 obreros construyen un muro en 45 minutos, entonces:

(15*R)*45min = 1 muro

Con esta ecuación podemos encontrar el valor R

R = (1 muro)/(15*45min)  

Ahora queremos saber cuando tiempo tardan 3 obreros en construir un muro, entonces tenemos que resolver:

(3*R)*T = 1 muro

Reemplazando el valor de R obtenemos:

(3*(1 muro)/(15*45min))*T = 1 muro

T = (1 muro)*(15*45 min)/(3*1 muro)

T = 5*45min = 225 min

3 obreros tardaran 225 minutos en completar el trabajo.
