How do you write one and three sevenths as a decimal?

Answer 1

1 and 3/7 can either be approximated/rounded or can be expressed as a repeating decimal. This is because the fractional component can not be expressed with a fixed number of digits to the right of the decimal point. This is similar to other fractions such as 1/3 or 1/9.

1 and 3/7 = 1.428571 428571 428571 (continues repeating infinitely).

Rounded versions include:

1.43, 1.42857, 1.4285714, etc.

A repeating decimal is often written with a horizontal line written over the repeated component. This would look like:

' ______ (note: the ' on this line was added to fix formatting)

1.428571

Answer 2

3.14
