In all natural numbers from 1 to 200, how many are multiples of 3, 4 and 5?

In all natural numbers from 1 to 200, how many are multiples of 3, 4 and 5?

The least common multiple of 3,4,5 is 3 × 4 × 5 = 60
A number that is a multiple of 3, a multiple of 4, and a multiple of 5 must be the common multiple of their three
Among all the natural numbers from 1 to 200, there are 60120180, a total of 3
I'm glad to answer for you. If you don't understand this question, you can ask,

Among the natural numbers from 1 to 100, how many are the multiples of 3 and 5?

The number of multiples of 3 is 3 69 12 15.99, and the number is 33
The number of multiples of 5 is 5 10 15 20.100, and the number is 20
The number of multiples of 3 and 5 is 15 30 45 60 75 90, and the number is 6
So there are 33 + 20-6 = 47 multiples of 3 and 5

The sum of a natural number and its reciprocal is 5.2______ ．

2 into a fraction is 515515 = 5 + 15, 5 × 15 = 1; so the natural number is 5

A method for refractometer measuring,in which a beam of rays emitted from a light source is transmitted to the interface between the optical window of a refractometer and the liquid to be measured, whereby part of the beam of rays is reflected back from the liquid and part is absorbed into the liquid and an image is produced in which the position of the boundary between a light and dark area depends on the critical angle of total reflection,the critical angle being a function of concentration of liquid, and in which the boundary between the light and dark area of the image is determined by light detectors arranged in a line.For good resolution, to the measuring data obtained from the light detectors is applied a mathematical model corresponding with the information provided by the measuring data and the position of the boundary is determined by means of this model.

A method of refractometer measurement in which a beam of light is emitted from the light source and transmitted to the interface between the optical window and the refractometer of the liquid, To measure a part of the reflected back beam of light from the liquid and a part of it is absorbed into the liquid and an image is generated in the boundary area between the position of a light and a dark angle depending on the limit of reflection, critical total as a function
The image of the boundary area between the light and the dark is arranged in a line by the photodetector. Because of the good resolution, the photodetector obtained from the measurement data is determined by applying the mathematical model and the corresponding information provided by the measurement data and positioning the boundary
