OpenStudy (studygurl14):
a lot of repeating numbers are a result of dividing by 9, or 99, or 999, etc.

That means this number is 37 hundredths, as a fraction 37/100
OpenStudy (studygurl14):
just a hint
OpenStudy (studygurl14):
@mathstudent55 the 37 is repeating
OpenStudy (anonymous):
so it would be 37/99 but how would i simplify that?
OpenStudy (mathstudent55):
Oh, sorry. Good call, @StudyGurl14 I didn't notice the bar on top to mean a repeating decimal.

you wouldn't. that's the simplest form
OpenStudy (mathstudent55):
Ok. For a repeating decimal, this is a way you can do to find a fraction.
OpenStudy (anonymous):
ok thank you
OpenStudy (studygurl14):
You're welcome
OpenStudy (mathstudent55):
2 digits repeat. We write a number that is a 1 followed by 2 zeros (same number of zeros as repeating digits)

We will use the number 100 soon.
OpenStudy (mathstudent55):
Call the number you are given x.
I'll switch to drawing so you can see the method.
