Answer 1

Answer:

Hello there!

Step-by-step explanation:

think of it as this way:

0

.

1

4

2

8

5

7

now, for every fraction, check the numerator. In this series, check the number which is the immediate largest of that number or, the same number with which it starts. Then, go clockwise in the decimal series starting from that number .So,

2/7 would be  0.285714 recurring

3/7 would be 0.428571 recurring

4/7 would be 0.571428 recurring

5/7 would be 0.714285 recurring

6/7 would be 0.8571428 recurring

Hope it helped you   :]
