Question

__

Answer 1

let x = 0.3636363636…

then 100x = 36.363636…

Subtract the two from each other you get

100x - x = 36.363636… - 0.363636…

Notice that the repeating 36s line up perfectly and will subtract out to exactly 0/

99x = 36 : Divide both sides by 99

x = 36/99 : Divide out the common 9 in both the numerator and the denominator

x = 4/11

Answer 2

Answer:

0.36 = 36/100 = 9/25

so the simplest form is 9/25
