how do you write __ 0.37 as a decimal in simplist form

OpenStudy (mathstudent55):

Once again, the 7 is in what place?

OpenStudy (anonymous):

100

OpenStudy (mathstudent55):

hundredths

OpenStudy (anonymous):

yes

OpenStudy (studygurl14):

a lot of repeating numbers are a result of dividing by 9, or 99, or 999, etc.

OpenStudy (mathstudent55):

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.

OpenStudy (studygurl14):

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)

OpenStudy (mathstudent55):

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.
