Question

Напишите периодические дроби,равные обыкновенным дробям:
24/30 , 36/48 , 4/7 , 45/63 ;
8/9 , 7/9 , 5/9 , 3/9 ;
123/999 , 12/999 , 5/999

Answer 1

24/30 = (3*8)/(3*10) = 8/10 = 0,8

36/48 = (3*12)/(4*12) = 3/4 = 0,75

4/7 = 0,(571428)

45/63 = (9*5)/(9*7) = 5/7 = 0,(714285)

8/9 = 0,(8)

7/9 = 0,(7)

5/9 = 0,(5)

3/9 = 0,(3)

123/999 = 0,(123)

12/999 = 0,(012)

5/999 = 0,(005)
