Answer 2

Step-by-step explanation:

Given: The number = 3/7

To find: Number of repeating digits in decimal expansion?

Solution:

So now since we have given the rational number, we need to find the value of 3/7.

So 3/7 = 0.42857142857142857142857142857143‬

A rational number can also be represented in decimal form and the resulting decimal is a repeating decimal.

Also any decimal number that is repeating can be written in the form a/b with b not equal to zero so it is a rational number.

So in the above value we find that the term 428571 is the repeating term, which is repeating 4 times.

Answer:

So, the number of repeating digits in decimal expansion of 3/7 are 428571
