Question

1/7= 0.142857. Can you predict decimal expansions of 2/7, 3/7, 4/7, 5/7 and 6/7, without actually doing the long division? If so, how?​

Answer 1

Answer:

Yes we can predict it by multiplying as follows.

Step-by-step explanation:

1/7= 0.142857 bar

So, 2/7= 2 x 0.142857bar

Which gives 0.285714 bar

3/7= 3x 0.142857 bar

Which gives 0.428571 bar

4/7=4x 0.142857 bar

Which gives 0.571428 bar

5/7 = 5 x 0.142857bar

Which gives 0.714285 bar

6/7=6 x 0.142857 bar

Which gives 0.85714 bar

I hope it is correct and will help you..

Here x means multiply sign

And bar is on all the numbers except 0
