Question

how do you change a rational number to a decimal

Answer 1

you want to change a fraction into a decimal, because there really is no way to change an integer into a decimal.

DO you want an explanation on how to do this in general, or do you have a specific problem that you are working on?

Answer 2

no

Answer 3

Lets say, you have a rational number \(\LARGE\color{black}{ \frac{3}{5} }\) and want to change it into a decimal.

we do our division in a table:

picture 1.

\(\huge\color{black}{ _{_{0.}} }\)
\(\large\color{black}{ {\text{_______}} }\)
\(\large\color{black}{ 5 }\) \(\large\color{black}{ {\LARGE |}3 }\)

Answer 4

picture 2.


\(\huge\color{black}{ _{_{0.6}} }\)
\(\large\color{black}{ {\text{_______}} }\)
\(\large\color{black}{ 5 }\) \(\large\color{black}{ {\LARGE |}30 }\)
\(\large\color{black}{ ^{^{-}} 30 }\)
\(\large\color{black}{ {^\text{_______}} }\)
\(\large\color{black}{ 0 }\)

Answer 5

See how I am dividing 3 by 5? so when I divide 3 by 5, I get 0.6.
That means that a rational number 3/5 can be written as a decimal, 0.6
