Question 5 of 5


 

The following transcript is provided for your convenience.

So, this number would be read as six hundred forty-one and five thousand one hundred twenty-nine ten thousandths. This number could also be represented as a mixed number. Six hundred forty-one and five thousand one hundred twenty-nine ten thousandths.

Let’s look at another decimal. 5.8139. We could write this number as an improper fraction by taking the 5, plus, this would be 8/10, since it’s in the tenths place, plus 1/100, plus 3/1000, plus 9/10000, which would give us 58139/10000.

So, we’ve seen a decimal in decimal form, we’ve seen it represented as a mixed number, and also as an improper fraction.
