Question

Стоимость линз в очках составляет 5\8 от полной стоимости очков,а робота по установке линз в оправу-в 5 раз дешевле.Какую часть от полной стоимости очков составляет стоимость оправы?

Answer 1

5\8x+1\8x=6\8x
Значит оправа стоит 2\8x

Answer 2

Calculation of the Frame Cost

To determine the portion of the total cost of the glasses that is attributed to the frame, we need to consider the information provided.

The cost of the lenses in the glasses is stated to be 5/8 (or 5 out of 8) of the total cost of the glasses. Additionally, the cost of the robot installation for the lenses is stated to be 5 times cheaper than the cost of the lenses.

Let's assume the total cost of the glasses is represented by the variable "C".

The cost of the lenses would then be 5/8 of C, or (5/8) * C.

The cost of the robot installation for the lenses would be 5 times cheaper than the cost of the lenses, or (1/5) * (5/8) * C.

To find the cost of the frame, we subtract the combined cost of the lenses and the robot installation from the total cost of the glasses:

Frame cost = C - [(5/8) * C + (1/5) * (5/8) * C]

Simplifying the equation:

Frame cost = C - (5/8) * C - (1/5) * (5/8) * C

Frame cost = C - (5/8) * C - (1/8) * C

Frame cost = C - (6/8) * C

Frame cost = C - (3/4) * C

Frame cost = (1 - 3/4) * C

Frame cost = (1/4) * C

Therefore, the cost of the frame represents 1/4 (or 25%) of the total cost of the glasses.

Please note that the specific value of the total cost of the glasses (C) was not provided in the question, so we cannot determine the exact cost of the frame without that information. However, we can conclude that the frame cost is 25% of the total cost based on the given proportions.
