Question

how do you turn a decimal into a fraction?

.1 = 1/10

As a decimal, you describe .1 as "one-tenth" because it means the same as 1/10

Get it?

Answer 8

what about writing this as a fraction:
\[.5124124124124\cdots\]
So first let
\[x=.5124124124124\cdots\]
So \[10000x=5124.124124124124 \cdots \]
So if we take the 2nd equation-10*1st equation we get
\[10000x-10x=5124.124124\cdots -5.124124124124 \cdots \]
\[9990x=5124-5\]
\[9990x=5119\]
so this means
\[x=\frac{5119}{9990}\]
But remember what we called x?
=>
\[\frac{5119}{9990}=.5124124124124\cdots\]
