Question

Is 5.5 greater then 5.7

Answer 1

no it is smaller.
think as to whether is .5 bigger then .7 as a whole integer
therefore 5.7 is bigger as it is close to 6 as a whole number than 5.5
trust this helps if not ask me to explain in a different way

Answer 2

No it is not. 5.7 is closer to 6, thus greater
