Question

Сколько существует натуральных значений в .при которых дробь (18+в) дробь 19 является правильной?

Answer 1

18 + B ≤ 19 
B ≤ 1 
B ∈ ( - бесконечность ; 1 ] 

Answer 2

Number of Natural Values for which the Fraction (18 over 19) is Proper

To determine the number of natural values for which the fraction (18 over 19) is proper, we need to find the values of '18' that are less than '19' and have no common factors other than 1 with '19'.

The fraction (18 over 19) is proper when the numerator, which is '18', is less than the denominator, which is '19'. Since '18' is less than '19', we can proceed to find the values of '18' that have no common factors other than 1 with '19'.

To find the values of '18' that have no common factors other than 1 with '19', we can use the concept of coprime numbers. Two numbers are coprime if their greatest common divisor (GCD) is 1. In this case, we need to find the values of '18' that are coprime with '19'.

The values of '18' that are coprime with '19' are: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17.

Therefore, there are 17 natural values for which the fraction (18 over 19) is proper.

Please note that the search results did not provide a direct answer to this question. However, the concept of coprime numbers and the relationship between the numerator and denominator of a fraction can be used to determine the number of natural values for which the fraction is proper.
