Step-by-step explanation:
1/7 = 0.142857 { GIVEN }
SO VALUE OF 2/7, 3/7, 4/7, 5/7, 6/7
2 × 1/7 = 2/7
=> 2 × 0.142857 = 2/7
=> 2/7 = 0.285714
IN THE SAME WAY,
=> 3/7 = 3 × 0.142857
=> 3/7 = 0.428571
=> 4/7 = 4 × 0.142857
=> 4/7 = 0.571428
=> 5/7 = 5 × 0.142857
=> 5/7 = 0.714285
=> 6/7 = 6 × 0.142857
=> 6/7 = 0.857142
