Lin has a marble that 5/8 inch wide. write the marbles width as a decimal. SHOW YOUR WORK
a_sh-v [17]
5/8 as a decimal would be 5/8 times 100/x because if you found the equivilent fraction you would be able to multiply it by the upside-down-fraction and get 1 for example 2/4 =1/2 if you multiply 4/2 with 1/2 you would get 4/4 or 1
so 5/8 times 100/x =500/8x=1
then use long division to solve 62.5/100=62.5%

Trabajando 10 horas por día, en 6 días se producen 3000 ruedas.

<h3>¿Cuántos dias tardarán en fabricar 3000 ruedas si trabajan 10 horas diarias?</h3>

Sabemos que trabajando 8 horas, en 5 dias producen 2000 ruedas.

El número total de horas que trabajan en esos 5 dias es:

(8 horas)*5 = 40 horas

Entonces se producen 2000 ruedas en 40 horas, es decir, la razon de trabajo es:

(2000 ruedas)/(40 horas) = 50 ruedas por hora.

Ahora, sí en la fabrica trabajan 10 horas al día, entonces van a producir:

10h*(50 ruedas por hora) = 500 ruedas por día.

El número x de días que deben trabajar para producir 3000 ruedas es:

x*(500 ruedas por dia) = 3000 ruedas

x = (3000 ruedas)/(500 ruedas por dia) = 6 dias.

Trabajando 10 horas por día, en 6 días se producen 3000 ruedas.
