Hint: square roots which are not whole numbers may be irrational eg sqrt 49 is rational ( =7) but sqrt 21 is not

OpenStudy (welshfella):

rational numbers can be written as a/b eg 3/4 is rational 0.54 is rational because it can be written as 54/100

OpenStudy (rockycatsrule):

oh so it is a # that cannot turn into a fraction correct

OpenStudy (texaschic101):

if u cant turn it into a fraction, it is irrational

OpenStudy (welshfella):

n be written as 46/100 so it is rational

OpenStudy (welshfella):

A*

OpenStudy (rockycatsrule):

so there for B is my answer right

OpenStudy (welshfella):

No sqrt 100 = 10 10/3 is rational

OpenStudy (rockycatsrule):

OpenStudy (welshfella):

OpenStudy (rockycatsrule):

D maybe if my recaculations made sence

OpenStudy (welshfella):

can we write 0.8 as a fraction?

OpenStudy (welshfella):

if we can then its rational

OpenStudy (rockycatsrule):

yes never mind also i am new at this

OpenStudy (welshfella):

ok dont worry I'm trying to get you to think about this . Thats a good way to learn.

OpenStudy (welshfella):

0.8 = 8/10 so its rational

OpenStudy (rockycatsrule):

but now i think i might have it. it is C because it is over pi

OpenStudy (welshfella):

over pi? yes it is C sqrt 8 can't be written as a fraction

OpenStudy (rockycatsrule):

oh ok thanks btw can u help with more if i close this question
