Question

Станок изготовливает 63 детали за 3 часа.за какое время этот станок изготовит 168 деталей

Answer 1

63:3=21 деталей за 1 час
168:21=8 часов
ответ за 8 часов

Answer 2

1 действием надо узнать сколько изготавливает деталей станок за 1 час-63:3=21
2 действием надо узнать за какое время станок изготовит 168 деталей-168:21=8 часов

Answer 3

To find out how much time it will take for the machine to produce 168 parts, we can use a proportional relationship between the number of parts produced and the time taken.

Let's set up a proportion:

Number of parts (63) : Time (3 hours) :: 168 parts : x (unknown time)

The proportion can be written as:

63/3 = 168/x

To find the value of 'x' (the time it takes to produce 168 parts), we can cross-multiply and solve for 'x':

63 * x = 3 * 168

Now, divide both sides by 63 to solve for 'x':

x = (3 * 168) / 63

x = 504 / 63

x = 8

So, the machine will take 8 hours to produce 168 parts.
