case a) the repeating decimal is 36

Let


x=0.1363636..

Multiply x by a power of
10, one that keeps the decimal part of the number the same:



1,000x=136.3636..


10x=1.3636..

Subtract
10x from
\\1000x



1,000x-10x=136.3636..-1.3636..=135

The repeating decimals should cancel out


\\990x=135

solve for x

Divide by
990 both sides


990x/990=135/990


x=135/990

Simplify

Divide by
45 both numerator and denominator


x=3/22

therefore

the answer case a) is

The fraction in simplest form is
3/22

case b) the repeating decimal is 136

Let


x=0.136136136...

Multiply x by a power of
10, one that keeps the decimal part of the number the same:



1,000x=136.136136...

Subtract
x from
\\1000x



1,000x-x=136.136136...-0.136136...=136

The repeating decimals should cancel out


\\999x=136

solve for x

Divide by
999 both sides


999x/999=136/999


x=136/999 -----> irreducible

therefore

the answer case b) is

The fraction in simplest form is
136/999
