Please help me with the steps of how to solve: Express /.45 as the ratio of two integers.

Question

anonymous · Answer

what is in the numerator? or should that not be there at all?

anonymous · Answer

No numerator. Just a line on top of .45.

unklerhaukus · Answer

$${1\over0.45}= {100 \over 45}$$

anonymous · Answer

That simple?

unklerhaukus · Answer

you can simplify further ,

unklerhaukus · Answer

$$={20 \over 9}$$

JaunitaM, it showed you "typing a reply" but it hasn't shown up... :/ Thanks for trying though!

anonymous · Answer

no he answered so I assumed it was good

anonymous · Answer

Thanks :)

I was looking at this opposite.  IE, if you divide 20/9 you get 2.22 not .45

if its a ratio = shouldn't they equal each other

directrix · Answer

If this diagonal has no relevance to the problem. {  /.45 }, then the question is to express .45 as the ratio of two integers. When read aloud, .45 comes out as 45 hundredths which is 45/100 which is the ratio of two integers. That does simplify to 9/20 because of the common factor of 5.

20/9 is incorrect, to the best of my knowledge.

directrix agreed - the line just meant repeating decimal.
