Пошаговое объяснение:

Правильная дробь, это когда числитель меньше знаменателя, если знаменатель равен 17, то:

4а + 1 < 17

4а < 17 - 1

4а < 16

а < 16 : 4

а < 4

Значения а должны быть меньше 4.

Значит все натуральные значения а, при которых дробь (4а+1)/17 будет правильной, это :

а = 1; 2; 3
