Question

Find an equivalent fraction for the decimal number.

0.4545

How do I solve it. It is a multiple choice so my choices are

5/11 9/20 2/5 45/100

Answer 1

since its in the ten thousandths place it would be over 10000
so it would be 4545/10000 and now we have to reduce and 100 x 100 = 10000 and 4545 / 100 = 45 so 45/100 is an answer 

Answer 2

0.4545 is equal to 4545/10000, basically.
then you simplify it. 
909/2000 

but since that's not in your answers, i'm guessing you have to round. your closest answer is 9/20.
