Answer 2

Answer:

$\frac{4}{7} = 0.5714 ...$

This is a non-terminating, non-repeating decimal expansion.

Explanation:

A decimal representation of a non-negative real r is its expression as a sequence of symbols consisting of decimal digits traditionally written with a single separator. The decimal expansion of variety is its representation in base-10 (i.e., within the decimal system). during this system, each "decimal place" consists of a digit 0-9 arranged such each digit is multiplied by a power of 10, decreasing from left to right, and with a decimal place indicating the s place.

The three different classifications of decimal expansion are terminating decimals, non-terminating repeating decimals and non-terminating non-repeating decimals.

A non-terminating, non-repeating decimal may be a decimal number that continues endlessly, with no group of digits repeating endlessly. Decimals of this sort cannot be represented as fractions, and as a result are irrational numbers. Pi may be a non-terminating, non-repeating decimal.
